Bruce Jenner has decided on his future female name

It's now Hollywood's worst kept secret that KUWTK star Bruce Jenner is transitioning to life as a woman.

Although his decision has been leaked from various sources – including Bruce's own mother, Esther Jenner – the reality star has yet to make any public statement himself.

However he recently pre-recorded a tell-all interview with Diane Sawyer in which he reportedly discusses his transition plans and reveals the name he will use as a female.

That name has not yet been publicly revealed, but previous reports have suggested it may be Brigitte or Belinda.

Although Bruce has been seen in public in recent months with longer hair, fuller lips, painted nails and even subtle diamond earrings, an insider said he "did not wear feminine make-up" for the interview.

When discussing the name he will use as a female, the source told Us Weekly that the 65-year-old "referred to her in the third person."

Bruce's step-daughter Kim Kardashian recently spoke out in support of the former Olympian, saying that she and her siblings "support Bruce one hundred per cent."

The recording Bruce's Diane Sawyer interview came just days after Bruce was involved in a terrifying car crash which tragically killed his neighbour Kim Howe. Since the accident, it's thought many old friends have reached out to Bruce, not just about the tragedy but about his transition.

"People who Bruce hasn't spoken to in forever are reaching out to him to offer support for his grieving process… But they are also letting him know that they support his transition too," a source told RadarOnline.

"Everything happens for a reason and Bruce is a firm believer in this. He was in such a great place before this happened and he will be in that place again after the dust has settled.''

Bruce himself released a statement earlier this week, offering his sympathies to Kim Howe's family. "I cannot pretend to imagine what this family is going through at this time. I am praying for them. I will continue to cooperate in every way possible," he said.

We're happy to hear that Bruce has finally made the decision to speak openly about his gender transition choice. The interview will air in May.
