Caitlyn Jenner Cover: Former Olympian Poses as Caitlyn for First Time on Vanity Fair

Say goodbye to Bruce Jenner and hello to Caitlyn.

Vanity Fair features Caitlyn on its July cover in white silk lingerie and long curly brown locks. The magazine posted a video clip of the photo shoot to its Instagram page.

"Watch Caitlyn Jenner pose for Annie Leibovitz in this exclusive behind-the-scenes video. Visit VF.com to watch the entire video, and tap the link in the bio to download the full article now. Video by @Jerelk. #CallMeCaitlyn," the captioned reads.

"Every day it always was a secret from morning until night," Caitlyn said in a voiceover for the video. "Caitlyn doesn't have any secrets. Soon as the Vanity Fair Cover comes out, I'm free."

Caitlyn also launched her Twitter account that has more than 1 million followers so far.

"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 tweeted.

Annie Leibovitz shot the photos of Caitlyn in her Malibu home while Pulitzer Prize winner Buzz Bissinger chronicles Caitlyn's struggle that made her into the woman she is today, according to Vanity Fair.

"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,'" Caitlyn tells Bissinger.

Jenner exclusively interviewed with Diane Sawyer back in April revealing the secret of transitioning into a woman, ABC News reported. In the interview, he talked about introducing her to the world soon but never gave an exact date.

"People look at me differently. They see you as this macho male, but my heart and my soul and everything that I do in life -- it is part of me," Jenner said at the time. "That female side is part of me. That's who I am."
