Shortly after Bruce Jenner introduced the world to Caitlyn, the Olympian's female identity, on the new cover of Vanity Fair today, she sent out her first tweet: "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 opened up further to the magazine about her transition, detailing her experience and emotions throughout the process.

"This shoot was about my life and who I am as a person," she tells Vanity Fair. "It’s not about the fanfare, it’s not about people cheering in the stadium, it’s not about going down the street and everybody giving you ‘that a boy, Bruce,’ pat on the back, O.K. This is about your life."
