"Call me Caitlyn," declares a headline on the July cover of Vanity Fair, with a photo of a long-haired Jenner in a strapless corset, legs crossed, sitting on a stool. The image was shot by famed celeb photographer Annie Leibovitz.
Caitlyn Jenner also debuted a new Twitter account with: "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."
The account broke a record for fastest time to reach 1 million followers, besting US President Barack Obama's new @Potus handle with a mark of 4 hours and 3 minutes, according to Guinness World Records.
Vanity Fair took to Twitter with the cover yesterday and said Jenner spoke emotionally about her gender journey: "If I was lying on my deathbed and I had kept this secret and never ever did anything about it, I would be lying there saying, 'You just blew your entire life.'"
The cover comes after Jenner's two-hour ABC interview with Diane Sawyer in which Bruce Jenner confirmed the transition.
Prior to the unveiling of Caitlyn, Jenner had said he preferred the pronoun "he", but Vanity Fair contributing editor Buzz Bissinger, who wrote the story, refers to "she".
The Olympian who married and divorced reality show "momager" Kris Jenner has appeared for years on Keeping Up with the Kardashians. Jenner's own still-untitled docu-series chronicling her transition is scheduled for entertainment channel E!, beginning on July 26.
"Everyone has been so supportive and so amazing and I think that that's all we could really ask for," said Jenner's stepdaughter, Kim Kardashian.
Jenner said she is aware of the appalling conditions in which many of the 700,000 transgender men and women live in the US and plans to shed light in the E! show on such issues as suicide and attempted suicide within the community.
