Question of the day: How would you feel if your father had a sex change to become a woman?

Bruce Jenner's evolving look has been the source of much speculation(waxed legs, lip injections, photos above)

Now comes word that the former Olympian's change is for real and that Bruce's ultimate goal is to live life as a female.

'Bruce is transitioning to a woman,' a family insider confirmed to People. '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.'

The 65-year-old has been pictured in recent days with manicured nails, smooth legs, longer locks and what appeared to be fuller lips.

The same source revealed that the Kardashian-Jenner family has been allowed time to get used to the idea, and that they're slowly accepting his decision.

'He's being very smart about and also respectful about his transition,' the insider said. 'Instead of completely shocking everyone, his changes have been subtle, and his family has had the chance to slowly get used to his new looks and life.'

'He has come out to those closest to him... He's been through a dark period and is coming out on the other side,' added the insider.

'It is an intense thing. Of course not everyone is 100 percent on board. Different people have different reactions. But everybody loves him.'

Bruce's journey is being explored for a new docu-series expected to air sometime this year.

'It will air when he is ready to be open about his transition,' the insider told People. 'But he's acting more and more confident and seems very happy."' 

Bruce has six children from his three marriages - daughters Kendall, 19, and Kylie, 17, with Kris Jenner; sons Brandon, 33 and Brody, 31, with ex-wife Linda Thompson; and daughter Cassandra, 34, and son Burt, 36, with ex-wife Chrystie Crownover.

And he has four stepchildren from his marriage to Kris: Kourtney, 35, Kim, 34, Khloe, 30, and Rob, 27.

A lot of people believe the desire to become a woman is a result of being henpecked for years by his wife but is that enough reason? And also being surrounded by ''vain'' women who are obsessed with their looks and this may have rubbed off on him...hmmm
