Kim Kardashian's step-father Bruce Jenner is transitioning into a woman – and the reality star has reportedly told his family that he has known he was meant to be a female since the age of five. 
TMZ reports that family sources have told the site that 'he has kept his "true self" inside since he was a child and even during the '76 Olympics.'
But the site adds: 'We're told Bruce has "never been female" in front of any of his kids. As for what that means, we're told in part he never wore female attire around the children.'
For now, the star has not yet revealed to his family what his new name will be and he apparently does not plan to reveal it during an interview with Diane Sawyer. 
Bruce and Diane are said to be in final talks to air an exclusive interview. 
No doubt Bruce has a lot on his mind at the moment – he was involved in a fatal car crash last week and the athlete turned reality star is trying to move past the harrowing accident.
The former Olympian was seen doing his usual morning routine on Sunday, and went to a coffee shop in Malibu where he picked up a hot drink and a yoghurt.
Bruce, who still appears to be growing his brown hair and wore it in a ponytail, was dressed casually in a black hoodie and trousers, with grey camouflage loafers.
The 65-year-old is transitioning into a woman, but he is yet to comment on the reports.
According to a new claim by TMZ, he also does not want his famous daughters to discuss his transition until he is ready.
The website alleges that Bruce believes some of the reports about him living as a female have come as a result of his transition being discussed during filming of Keeping Up With The Kardashians. 
It is claimed that the star is planning to film a docuseries that will follow his transition, and TMZ reports that he fears what he says about it on the E! program will be leaked during filming. 
However, Bruce is said to be conflicted, because he is aware that Keeping Up With The Kardashians can generate interest in his own show.
TMZ alleged earlier this month that the family will not be doing any press for the tenth season of their series, which is scheduled to premiere in spring, in a bid to avoid questions about Bruce transitioning into a woman.
His stepdaughter Kim Kardashian told Entertainment Tonight last month:
'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.
'I guess I'll kind of let everyone be curious and I feel like that's his journey to talk about, I just think it's his story to talk about, not really mine.'  
Bruce has six children from his three marriages – daughters Kendall, 19, and Kylie with Kris; sons Brandon, 33 and Brody, 31, with ex-wife Linda Thompson; and daughter Cassandra, 34, and son Burt, 36, with ex-wife Chrystie Crownover.
He also had four stepchildren from his former marriage to Kris: Kourtney, 35, Kim, 34, Khloe, 30, and Rob, 27.
While Bruce's family are said to have been fully supportive of his decision to live as a female, legendary poker player Doyle Brunson said the Olympic gold medallist is no longer his 'hero'.
