Bruce Jenner unveiled as a woman on Vanity Fair cover and describes panic attack after 10-hour surgery

Bruce Jenner has been unveiled as a woman on the cover of Vanity Fair. 

The 65-year-old former decathlete 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. (She is understood to have avoided spelling the name with a 'K' in an effort to create an identity separate to the Kardashian clan).

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. 

But after calling a counselor from the Los Angeles Gender Center, who made a house call to Jenner's Malibu home, she realized the doubt and second-guessing was 'human and temporary'. 

In fact, she said that shooting the cover was better than winning the Olympics.

'That was a good day, but the last couple of days were better,' Caitlyn told the magazine. 

Famed photographer Annie Leibovitz shot the cover at Caitlyn's palatial Malibu home. Leibovitz is one of the most renowned celebrity photographers, having shot many classic covers for Vanity Fair, including Demi Moore posing naked when pregnant. 

Inside the magazine, Caitlyn is pictured wearing five more outfits and in an accompanying YouTube video, which shows the shoot taking place, Jenner talks about her relief at having no secrets anymore.
