There are many athletes in various sports that are considered to be the greatest of all-time. We are fortunate to be living in an era where we get to watch these athletes perform on a regular basis. And while someone like Tom Brady in the NFL may be more popular, there's no question that in the world of female tennis, you don't get any better than Serena Williams.

Whether it's teaming up with her sister Venus or smashing the competition on her own, Serena has been a dominant force throughout her career. Perhaps the only reason Serena hasn't accomplished more at this point in time is the emergence of Alexis Ohanian in her life. Better known as the co-founder of Reddit, the two were married in November 2017. But not before also welcoming a baby girl, Alexis Olympia, into the world back in September 2017.

If you weren't jealous enough of Alexis for getting to be married to such an amazing athlete, you're going to become even more jealous when you see the 15 photos of Serena Williams that are sure to drive him crazy. She has appeared in various modelling photoshoots, and by the time you get through this list you will understand why.

Because perhaps not shockingly, having to be in good enough shape to be the best female tennis player of all-time, also leads to a career with several moments where she is sure to leave you stunned with how beautiful she is!

15 15. Rocking A Nike Advertisement

Serena Williams has had many lucrative sponsors over the years. But one of her favourites may be her connection with Nike. The company even stepped up by making her bedazzled wedding shoes! Which you can imagine would have made her wedding day a heck of a lot more manageable.

But as impressive as those shoes were, you might prefer getting to stare at this promotional shot by the company for some of their athletic gear. The photo shoot was taken in Los Angeles back in February 2014. It ended up being a pretty rainy day on set, but something tells us Williams' presence still made for one of the better days at work of the photographer's life.

14 14. Modelling For Her Fashion Line

It's obvious that in the sporting world that there aren't many females out there who can compare to Serena Williams. But she's not just content to stick to that world. She helped steal the show back in 2015 when she showed off some of the designs from her own fashion line.

When talking to Vogue.com about her line, Williams revealed "I’ve always loved fashion. I was always that girl that played with my dolls, and I went to fashion school, so it’s not just made up for me. It’s actually something that I really enjoy and that I have a lot of fun with." Imagine being a wildly successful tennis star who also has the creative drive to run a fashion line. Impressive, to say the least.

13 13. Showing Off Her Flexibility And Abs

Serena Williams is known to leave you impressed with the athletic moves that she pulls off when she is on the court. But she may be looking even more impressive as she shows off her flexibility for our next entry. She probably just hopes that she never needs to pull out a full-on split during a match!

It shouldn't come as a surprise that Williams has abs of steel, but that doesn't make her any less impressive to check out (or harder to stop staring at!). The photos were taken back in August 2015 and appeared in New York Magazine. Perhaps when she gets tired of tennis she'll spend some time engaging in gymnastics! We may see her at the summer olympics competing in two sports some time soon.

12 12. Beautiful In Blue

Serena Williams has had many moments in her life where she's left little to the imagination. One of her most popular came when she elected to pose for Sports Illustrated back in 2017. As much as people love a nice blue sky, it doesn't come anywhere near the beauty of Serena in a blue one piece.

When talking about getting ready for the revealing photo shoot, Williams admitted that she took special preparation! "I cut back a lot on carbs and did a lotttt more cardio! I always try to watch what I eat and I typically eat relatively healthy, but I knew I had to get really serious for this." The results definitely look like they paid off, as people the world over still look at this photo in awe.

11 11. Sportsperson Of The Year

Serena Williams is no stranger to receiving various accolades for her accomplishments. And while we are sure she doesn't sit back and rank her different trophies, one of her favourites may have been when in 2015 she was named Sports Illustrated's Sportsperson of the Year. The recognition also came with an appearance at the ESPY's where Serena left people empowered not by just what she accomplished on the court, but with her words.

She said "I’ve had people look down on me, put me down because I didn’t look like them — I look stronger. I’ve had people look past me because [of] the colour of my skin, I’ve had people overlook me because I was a woman... and I’m still going". She is truly a great role model and an inspirational figure.

10 10. Perfect In Pink At ESPYS

Serena Williams has gone through a tremendous amount of adversity in her life. This includes battling a pulmonary embolism that led to her taking a significant break from action on the tennis court for close to a year.

She came back strong and won at Wimbledon adding yet another impressive layer to her legacy. She then proceeded to steal the show again when she appeared at the 2011 ESPY Awards only a few months later. When talking about her appearance at the time, Williams said "I wanted to get really fit. I wanted to lose some weight. So I’ve been doing Pilates and yoga, trying to lean out my body so I won’t be bulky". She clearly always strives to be more fit and strong, and that explains her run of success.

9 9. Leaving Little To The Imagination In Milan

There are many things that are fantastic about being in North America. But if you want to look at where the bulk of some of the high fashion is produced in the world, it's done outside of Canada and America. Which also means naturally that some of the biggest fashion shows of the year take place around the globe.

Serena was one of many celebrities who were more than happy to jet set off to Milan to take in Fashion Week back in September 2016. We suppose it helps that she's had a career where she has made upwards of $100 million. Not to mention Reddit isn't exactly a small company so Alexis is also pretty comfortable financially! The above photo was taken when Serena was on her way to a Gucci show.

8 8. Ravishing In Red

One of the biggest events in Hollywood every year is the Oscars. And even though Serena Williams hasn't shown her talent in the world of acting, that doesn't mean she misses out on the event. The above photo was taken at the Vanity Fair Oscar Party back in 2015. We're sure Williams was surrounded by other gorgeous women, but it's hard to imagine anyone looked as radiant as she did.

Let's just hope Alexis is into the party scene because Serena's popularity in the world isn't slowing down anytime soon. Perhaps they can use their adorable baby to help get them out of events if they're not feeling up for it though! Given how much money they both have made, it shouldn't be too hard finding a baby sitter.

7 7. With A Racket In Hand

We are sure that there is no shortage of outfits that Serena Williams can put on and leave Alexis in a good mood. But we wouldn't be too shocked if he first took a liking to her by seeing how tremendous she looks on the tennis court.

Though if Alexis went up to her and tried to get her attention by calling her Serena, he may have been out of luck. Because off the court, Serena goes by (or at least did at one point) another name "I'm Serena Williams on the court, but away I have so many different names. I call myself Butterfly," said Williams in an interview. That may cause some confusion, but we're sure Alexis doesn't care which name she wants to go by.

6 6. Staring The Camera Down In A Meshed Top

When you take a look at the above photo, you may see several features of Serena Williams that stand out to you as appealing. And as if she wasn't good looking enough, she clearly has a pretty excellent sense of fashion. Serena definitely has confidence in her appearance now, but she also knows that learning to love herself was not an easy process.

She states: "I love who I am, and I encourage other people to love and embrace who they are. But it definitely wasn't easy - it took me a while," said Williams to DeJour. We're sure that having a tremendous husband like Alexis helps making love herself even easier. They clearly are a very happy couple.

5 5. Looking Like A Winner At Wimbledon's Winners Ball

Serena Williams had plenty of reasons to smile when she attended the Wimbledon Winners Ball back in February 2016. She was coming off two victories at Wimbledon, both as a singles competitor and alongside her sister Venus in the doubles competition.

You can imagine the women that have to go up against not only one, both Williams' sisters must be getting pretty frustrated by this point! Talk about taking that whole "twin power" to a whole new level. Though if there are any young twins out there who are aspiring tennis players, you can't get better inspiration than these two.

4 4. Admiring Herself

If you look at most women in selfies, their focus is on the camera or on the mirror in front of them. But for Serena Williams, it's what is behind her that appears to have been what caught her attention. Hard to blame her though, as she probably isn't the only person who is guilty of being caught staring at her prominent features on that day!

Considering the photo eventually made its way online, it's clear that she was at the very least happy with the end result of how that dress made her look. But when you factor in that the photo was taken in what appears to be a washroom, let's hope it didn't take her too long to take the photo or someone may have gotten impatient!

3 3. Showing Off For A Photo Shoot

It's clear in this entry that the photographer wanted to highlight just how strong Williams is. In particular, her strong legs that have surely serviced her well over her long career.

But when talking about her biggest insecurities with People.com, Williams revealed "My thighs. I think they’re too big. But also my arms. I think they’re too muscular. They’re too thick." Williams also stated that she struggles with her workouts sometimes and feels extremely insecure about her body a lot of the time. She has managed to fight through it though, being able to perform photoshoots like the one above. She continues to be an inspiration to women everywhere for showing that beauty and muscle can co-exist.

2 2. Paparazzi Spotted Her Looking Fit

Serena Williams must feel right at home when she is walking around in athletic pants. Unfortunately, she must also be plenty comfortable with the idea that everywhere she goes, paparazzi is probably going to be quick to follow. That tends to happen when you are one of the most famous athletes every to play any sport.

Especially because the sight of Williams in those pants is something that the tabloid papers and their viewers are probably going to be very interested in. You just need to hope that in the future that if she is out with her daughter that the paparazzi will give her a wide berth; or face the wrath of one of the most dominant athletes of all-time.

1 1. Relaxing With Baby Alexis

There are many things that Serena Williams is proud of. But one of the things that stands out to her above all else is her love of family. Which is why if there is any single photo that really makes Alexis' heart warm, it's this adorable photo of Serena with their daughter who is also named Alexis.

Serena and Alexis (baby version) appeared in Vogue's February 2018 edition. When discussing the importance of family in the past, Williams revealed "Family's first, and that's what matters most. We realize our love goes deeper than the tennis game". Considering his sister actually was one of her fiercest competitors, it is good to know that she appreciates the value of family relationships.
