The Kardashian patriarch once known as Bruce Jenner will be on the cover of the next Vanity Fair with a new identity: Caitlyn Jenner. (That's Caitlyn with a C, not a K, interestingly enough).

“I’m so happy after such a long struggle to be living my true self,” Jenner posted using a brand-new Twitter handle, @Caitlyn_Jenner. “Welcome to the world Caitlyn. Can’t wait for you to get to know her/me.”

A message from Caitlyn’s new Facebook page read, “Everybody has challenges in dealing with life. I’m so happy after such a long struggle and finally living my true self.”

“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,’ ” Jenner said.
