Bruce Jenner told his daughters about his sex change in front of cameras in an emotional family chat, according to reports.

The former Olympian is said to have been very “matter-of-fact” as he made the shock revelation to his family, following months of speculation over his changing appearance.

The moment will reportedly be shown on a future episode of Keeping Up With The Kardashians.

A source told Us Weekly: “He literally started the conversation with, ‘Hey, guys, I’m becoming a woman, but I’m sure you probably already figured that out’.”

The star has undergone a complete transformation in recent months, following his split from Kris Jenner, growing his hair out and even having his Adam’s Apple flattened.

Changing appearance

“There was so much speculation, and they were all wondering about the truth,” the source added. “Bruce had to address it with them.”

It comes amid reports Bruce will open up about his sex change in a tell-all interview with Diane Sawyer, as well as filming his own docu-series about the decision.

“He got a little emotional, but it wasn’t a jaw-dropping conversation,'” the source went on, adding: “It’s a surprise to the girls that he’s doing this at 65.”

All of his daughters are said to have been very supportive of his decision.

Split from Kris

Bruce’s “journey” could cost him $250,000 if he’s going to make the transformation from male to female.

The former Olympian was reportedly shooting a documentary about his life as he makes some big changes , with his mother 88-year-old Esther Jenner confirming the news that Bruce was making the change.

Now a top Beverly Hills surgeon has given an estimate for how much treatments could cost Bruce if he decides to go ahead with full gender reassignment procedures.

Dr Ashkan Ghavami, who has not treated Jenner but is a board certified plastic surgeon, has explained the extensive treatment process that transitioning from a man to a woman entails.

“Hair removal on his face or chest, where at least 8 to 10 sessions are sometimes needed, could total from $2,500 to $5,000,” Dr. Ghavami told RadarOnline.
