PEOPLE on Friday reported that it has confirmed that Bruce Jenner will soon be living life as female.

“Bruce is transitioning to a woman,” an unnamed source is quoted as saying. “He is finally happy and his family is accepting of what he's doing. He's in such a great space. That's why it's the perfect time to do something like this.”

According to a second source, Jenner's journey will be the subject of a documentary.

“It will air when he is ready to be open about his transition,” the source said. “But he's acting more and more confident and seems very happy.”

The 65-year-old Jenner won the gold medal in the decathlon at the 1976 Summer Olympics in Montreal and subsequently found success in television. The long-running reality series Keeping Up with the Kardashians focuses on the lives of the Kardashian-Jenner family.

Stepdaughter Kim Kardashian told ET: “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.”

Jenner has married three times, has six children and four stepchildren.
