Bruce Jenner is ready to begin living life as a woman. The patriarch of the Kardashian family, also one of the stars of the reality show “Keeping Up With the Kardashians,” had been the target of speculation and rumors for months due to his increasingly feminine appearance, but a source confirmed that he has begun the transition in earnest. “Bruce is transitioning to a woman,” said the source. “He is finally happy and his family is accepting of what he’s doing. He’s in such a great space. That’s why this is the perfect time to do something like this.”

“He has come out to those closest to him,” adds the source.

Kim Kardashian, Bruce’s stepdaughter, recently appeared on Entertainment Tonight and was asked about Jenner’s changing appearance. The reality-TV princess confirmed that her stepfather was going through a “journey” and that it was his story to tell when he was ready.

“I think everyone goes through things in life, and I think that story and what Bruce is going through, I think he’ll share whenever the time is right,” said Kardashian. “I feel like that’s his journey to talk about. … He’s our dad so we support him no matter what.”

Tabloid magazine In Touch received harsh criticism recently for releasing an issue with Jenner on the cover in Photoshopped makeup and clothing with the title “My Life as a Woman.” Other publications have taken a more respectful approach: Us Weekly recently ran a cover story titled “Bruce’s Brave Announcement,” which shared supportive quotes from family and had a more positive tone.

Confirmation of Jenner’s transition comes just days after news broke that the former Olympic athlete would be headlining a new reality show documenting his life.
