Bruce Jenner has revealed the name he will now be using going forward as he makes his final transition into being a woman.
On the cover of Vanity Fair, the former Olympian unveils a brand new body - complete with a boob job and the kind of hourglass curves we would kill for - and reveals his new name is Caitlyn.
Notice how she chose not to spell her new name with a K?!
Caitlyn was rumoured to have had breast enlargement surgery late last month and was thought to be recovering quietly at home, cared for by a team of nurses.
In a behind-the-scenes video, Caitlyn admits that living every day as Bruce was "living that lie".
"Caitlyn doesn't have any secrets. Soon as the Vanity Fair cover comes out... I'm free."
Caitlyn has already got a verified Twitter account, and used it to introduce herself.
Welcome to the world, Caitlyn Jenner!
