Bruce Jenner is no more, and the 65-year-old former Olympian debuts as a woman on Vanity Fair's July cover in an Annie Leibovitz photo with the headline "Call me Caitlyn." VF sent Leibovitz and Friday Night Lights author Buzz Bissinger to Jenner's place in Malibu, where they got "unfettered access." "If I was lying on my deathbed and I had kept this secret and never ever did anything about it," Jenner tells Bissinger, "I would be lying there saying, 'You just blew your entire life.'" Jenner also debuted @Caitlyn_Jenner, tweeting, "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." She had 153,000 followers in her first 40 minutes. The issue of Vanity Fair is out June 9. (More Bruce Jenner stories.)
