When you think of the MMA, you think of kicks to the face, endurance, and ultimately: survival of the fittest. One of the most well-known MMA fighters today is none other than "Mystic Mac" himself, Conor McGregor. McGregor has made a name for himself with his moves inside the octagon and his rather outlandish statements outside of them. In the MMA world, he is just about as unbeatable as they come. In his 24 bouts in his MMA career, he has won 21 of them. He has won 18 by knockout, one by submission, and two others by decision. It is easy to say he is good at what he does in the MMA world. Of course, there are the doubters after he lost to Floyd Mayweather Jr. in the boxing ring. However you view him, Conor McGregor has come a long way from being a little lad from Ireland. He also has a really good looking girlfriend and two very good looking sisters.

Conor McGregor has two sisters in his family. One is named Erin while the other one is named Aoife. He also has been in a relationship for a decade now with a woman named Dee Devlin. These three ladies have been through everything with Conor from his broke days to his now wealthy days with having sponsors from companies like Reebok and Monster Energy. But shouldn't we get a little bit of a better look at the strong women in MeGregor's life? Let's take a look at 10 pictures of Conor McGregor's sisters and 10 of his girlfriend, Dee Devlin.

19 Erin McGregor: Dressed in Black

The first photo of the McGregor sisters comes in the form of the older one, Erin. Erin has had quite the life that doesn't really get seen because of her brother Conor's success. She was a hairstylist a long time ago before she made a major change. Now, she is a fitness model and a bodybuilder which is quite the change. From the beauty salon to the gym all the time she went and now she has great photos like this.

She is wearing a black dress with a big smile on her face. She looks absolutely breath-taking with this particular photo. She appeared on "Dancing with the Stars"and she ended up making it to the semi-finals. We will see her in plenty of beautiful dresses like this one. Hopefully, she has the dance skills to match also!

18 Dee Devlin: All Irish Girl

Behind every great man is an even greater woman. That is the case with Conor McGregor's girlfriend, Dee Devlin. Devlin has been with McGregor for about nine years now. She was in love with Conor before he became a big UFC star. He didn't have anything way back when they started dating. But, she stuck by his side and is now grasping in the glory of being a famous UFC star's girlfriend. She also is very good-looking too.

She has a little bit of a smirk on her face with a black undershirt and pink top on. She probably is smirking about the next vacation she is going to take with Conor. She shows just how good-looking she is without doing much in the picture. She also shows love can withstand all obstacles and be worth it in the end.

17 Aoife McGregor: Close Up

Now that we have met Erin McGregor, it only makes sense to meet the younger sister in Aoife McGregor. But what exactly does Aoife do? Well, she is working with a mini digger hiring company in Dublin, Ireland. If you are hoping for a chance with her gentlemen, you are out of luck as she married her long time love, Mark Elliot, on New Year's Eve. She does continue to dazzle us though with excellent pictures like this one.

The wedding ring is evident in her hand in this one. She also has a slight smirk on her face along with her blonde hair flowing effortlessly off of her. Her eyes also sparkle in this photo which makes her a vision of loveliness, close up. She definitely is making the case for better looking sister.

16 Dee Devlin: Mirror Mirror On The Wall

Dee Devlin is the type of woman all men need in their lives. She is a good woman who worked hard and provided for herself along with her man while he went out and worked hard toward his dream. Obviously, she is cashing in with all of the money coming in from fighting and sponsors that Conor does. Now, she can post as many selfies as she wants, enjoying the good life like she does above.

Her hair is flowing beautifully with a little bit of mess going on. Her smile is on point as we see her pearly white teeth in this one. She also has a nice mirror in the background to be able to see just how far she has come from nearly a decade ago. The money will keep coming in and Dee will continue to take great selfies like this.

15 Erin McGregor: Bodybuilding's Paying Off

Like we said before, Erin McGregor is a woman of many talents. She can probably still give a great haircut if you book with her in advance. But now, she is taking her talents to competitions with a body like this one she made through commitment and sacrifice. She certainly does know how to light up a room with her smile and body in this next particular photo.

Like we said before, her tenacious look is clear in this. We tend to forget Erin styled Conor's man bun that he went into some fights wearing. But now, she can focus exclusively on her career as a bodybuilder and put out stunning photos. If you think she looks good here, you should see her during a competition!

14 Dee Devlin: Ready for a Night Out

We have said it before and we will say it again, Dee Devlin had to go through a lot that no woman should have to go through. She had to work her butt off to get everything she wanted before Conor got his big break in the UFC world. Now, she can relax and ride the wave of money that Conor continuously brings in for her and their family. In this next photo, she is ready for a night out.

She has a black dress on with splashes of paint along with silver heels and her purse ready to go. For everything she went through, we are glad she is living a good life where she is stress free for the most part. She also looks stunning all dressed up and ready for whatever the night offers her. Dee definitely did herself up well here!

13 Aoife McGregor: Soft Smirk

When a Conor McGregor fight goes on, he has the best support system in the world. His girlfriend, parents, and sisters all come to as many fights as they possibly can. Of course, they all have their own lives to live as well. Aoife McGregor is now married and enjoyed her honeymoon in the Maldives with her husband. Now, the honeymoon is over and she has to continue on with her career. But that doesn't mean that Aoife still doesn't have time to put up marvelous pictures.

She is sitting and leaning back against a wall while looking at the camera. She has a black dress on with her legs extended out. She is simply a vision of loveliness for all to look at. But, she is happily married, so looking is as far as somebody will get. She probably has a move or two up her sleeve that Conor has used in the case of a hands on fan.

12 Dee Devlin: Cheetah Look

Cheetah print is one of the most interesting types of style out there. There seems to be cheetah print for just about anything these days, blankets, coats, you name it. Dee Devlin shows that she doesn't mind putting on some cheetah print while smiling bright for the camera. This next photo shows just how good cheetah print can look on the right lady in the right situation.

Dee Devlin is in a car, sitting in the seat with her cheetah print shirt on and smiling for the camera. She didn't even put a caption on her Instagram post of it because quite honestly...she didn't need it. She can get the finer things in life now thanks to hubby Conor. But she has to pull off the look all on her own, and she does a great job of that here.

11 Erin McGregor: Lifting Weights

Erin McGregor admitted that it took a lot of sacrifice when she went into the world of bodybuilding. She certainly isn't wrong with this claim. There has to be a strict diet followed and a strict workout plan developed to look and feel like she is ready for competition. We get a glimpse of Erin McGregor in the gym in this next photo and boy is it something!

She is wearing a black and white sportss bra with a hint of neon green showing underneath. She is smiling at the camera as she effortlessly curls 50 pound weights. She has that look of confidence in her face like she is going to win her next bodybuilding competition or how Conor must feel going into his next fight. She probably will win her next competition too with all the hard work done.

10 Dee Devlin: Throwback to the Gold Purse

We all love a little bit of a throwback every now and then. This isn't exactly a throwback to years ago when they were struggling financially when only Dee was working. But, this is a throwback to nine months ago where we get to see a little bit of the reward that comes with being Conor McGregor's long time girlfriend.

Devlin is wearing a grey top with a white and gold skirt along with a pair of black heels. The most glaring image in this photo though is the gold purse that Devlin is holding in her right hand. She has the look of determination in her eye, ready to go out either to her hubby's fight or maybe just out for a fun date night. Whatever the case is, Dee Devlin looks really good in this photo, quite simply.

9 Aoife McGregor: Having Fun at the Beach

It can't be all work and no play in the McGregor household. The McGregor kids have to go out and enjoy life. After all, they are all in some way benefiting from Conor making millions of dollars, even if one of those occasions came from a knockout by Floyd Mayweather Jr. All jokes aside, it seems like Aoife McGregor is enjoying herself in this particular photo with pool umbrellas all around and the sun beating down on her.

She has her long, blonde hair wrapped in a pony tail along with a white bathing suit top while enjoying the day. Her flat stomach makes an appearance, so it shows she likes to go to the gym like her older sister Erin does. She is smiling all the way into the arms of her husband as they can enjoy days like this for a long time.

8 Erin McGregor: Dancing with the Stars

Like we said before, Erin McGregor made it to the semi-finals on "Dancing with the Stars". If you have seen it before, it can be quite the treat for the celebrities who have had little dancing experience in their lives. We do not know how McGregor will do until we see her first routine. But we do know that she will look stunning like she always does. She gives a glimpse of what fans can look forward to when she takes the stage.

She is wearing a black long sleeved top along with a red skirt and showing off a confident smirk. If you were Erin McGregor, why wouldn't you have a smirk? You compete in bodybuilding competitions, you have a great family, and your brother is one of the biggest stars in the UFC. That would certainly make me smile knowing I have all of that going for me.

7 Dee Devlin: Ready To Go

One of the biggest parts of being a UFC fighter is being able to have endurance. Endurance comes from doing countless hours of cardio and being able to stay on your feet. Dee Devlin isn't necessarily fighting for her life or even for money in this next particular photo. But she is showing off a lot of her legs with it.

Dee Devlin is sitting down while wearing a white lace top and blue shorts while wearing a pair of white sneakers. She also has a tattoo very much present on her left thigh. She looks like she could be heading out to run errands or go spend some time with Conor and family. Whatever the case is, Devlin is looking good and shows her legs off very well when it's all said and done.

6 Aoife McGregor: In Paradise

Aoife McGregor can pretty much wear whatever she wants and people are going to be going ballistic over it with their jaws dropped as well. In this next photo, it looks like she is enjoying some vacation time. Whether it was on her honeymoon or on a family vacation still remains a mystery. But what isn't a mystery is just how good she looks in this particular photo.

She is wearing a one piece red bathing suit that has the word 'wifey' on it. If the implication is, she's wifey material, we certainly agree. She also has her blonde hair flowing down and sunglasses on while relaxing on a boat. It is amazing how good Aoife looks while simply enjoying some nice weather. She definitely makes it a tough case to decide which McGregor sister is better looking between the two.

5 Dee Devlin: Casual Black Dress

Dee Devlin must be loving life now these days. Think about her life now and then think about how it was about a decade ago. Nearly a decade ago, she was working to try and support two people. Now, she does have to worry about money probably ever again. She loves life so much that she even put a heart in her Instagram post for all to see.

She is in her room wearing a casual black dress while smiling for the camera. She looks so good that it is no wonder why Conor McGregor has had her as his girlfriend for nearly a decade, besides the fact of how faithful she was to him. This really can be a true rags to riches story. Well now, Dee Devlin can enjoy wearing her little black dress and look so good in doing so as well.

4 Erin McGregor: Chilling in Vegas

Back in the summer, the biggest story in the sports world was that Conor McGregor had finally gotten the fight he had been lobbying for years, as he and Floyd Mayweather stepped in the ring together. Before the fight, McGregor's family had their share of fun in Vegas.

Erin is showing a lot in this photo, as she enjoys a great day in the Vegas sun, anticipating her brother getting into the ring with a boxing legend. There is a lot of love that goes around between everyone that is a member of the McGregor family. Erin will surely find love with the looks and determination that she all has going for her. For now though, she might as well enjoy all the quality time she can get with her loving brother.

3 Dee Devlin: Shopping Away

Sometimes when you have a lot of money, you just have to spoil yourself. For the common working person, it can be buying a nice, luxurious gift when a good some of money comes back during tax return. For others, it could be hitting big on a scratch ticket. For Dee Devlin, it is enjoying the income that Conor brings for her and their family. She definitely knows just how spoiled she can be in this next photo.

She is wearing a grey t-shirt with a black skirt and black boots on with her shopping bags visible. She put the angel face emoji and the term "spoilt" in her Instagram post, so she knows she has a very luxurious lifestyle. It doesn't hurt to buy some nice gifts after going through everything they did over the past decade or so.

2 Aoife McGregor: The Best Sibling?

It is certainly hard to find someone with the whole package. The old saying goes that you have to kiss a bunch of frogs before you find your king/queen. It isn't like people are putting the terms "wifey" or "husband material" on shirts for all to see. Well, Aoife McGregor definitely is wife material, but she already has a ring on her finger. But, we can still enjoy how great she looks in this next photo.

She lives a pretty good life just like her brother Conor and she is wife material to top it all off also. It's gotta be crushing to a lot of men's hearts that she's taken. Too bad the ship has sailed on fans to have a chance at being Conor's brother-in-law.

1 Dee Devlin: Getting Her Work in at the Gym

Imagine all of the work Conor McGregor had to put in over the years to get himself ready to be a professional fighter. Well, he needs a girlfriend that can be able to catch up with that type of lifestyle. Fortunately for Conor, Dee Devlin fits that type perfectly. In this next photo, she isn't shopping, dressed up, or in a bikini. But, she is looking very good while getting her daily workout in.

She is wearing a purple sports bra with her hair tied up and black yoga pants and white sneakers to complete the outfit. She shows just how hard she is working. But, she also shows she can have some fun by snapping a quick photo of herself. Conor McGregor really did well with Dee Devlin and I cannot wait until he finally asks her to be his wife for all eternity.
