Even though she's the daughter of the legendary Ric Flair, Charlotte's last name has mostly been kept silent since debuting in WWE. This past week on RAW though, GM Mick Foley introduced the former Women's Champion as 'Charlotte Flair'. In an interview with Lita last week, Charlotte was also addressed by Lita as 'Charlotte Flair'. It seems this is no coincidence, as the iconic 'Flair' name has been added to Charlotte's WWE profile page, as well as her Twitter account.
Usually WWE changes names to make them shorter, i.e - Big E Langston to Big E, Antonio Cesaro to Cesaro - so this is a little uncommon. Perhaps it's to further hammer home that they want Charlotte to carry the Flair name.
