Bruce Jenner, 65, has been unveiled as a woman on the cover of Vanity Fair.
Kim's step father is wearing a silky white basque, which reveal the results of Jenner's recent 36D breast implant surgery.
It also reveals Jenner's new name for the first time - Caitlyn.
The reality TV star also set up a verified Twitter account under Caitlyn Jenner - quickly amassing more than 1 million followers - where she shared her cover and wrote: 'I'm so happy after such a long struggle to be living my true self.
'Welcome to the world Caitlyn. Can't wait for you to get to know her/me.'
During the Vanity Fair interview, Jenner revealed she had a panic attack at one point during the transition.
'"What did I just do? What did I just do to myself?'" Caitlyn told author Buzz Bissinger she was left wondering, after waking up from a 10-hour facial feminization surgery on March 15, worried she had gone too far.
