Bruce Jenner to reveal his transition into a woman during an interview with Diane SawyerGetty Images

Olympic champion Bruce Jenner will reportedly announce his transition into a woman during his highly-anticipated interview with ABC's 20/20 host Diane Sawyer.

The 65-year-old has never responded to the transgender rumours, despite the fact his image appears to have grown increasingly feminine, claims he has had breast implant surgery and photos emerging of him allegedly wearing a dress.

However, he is expected to finally explain all about his "journey" in his two-hour special with Sawyer, which is set to air tomorrow (24 April).

If Jenner has decided to live his life as a woman, he will no doubt have an abundance of support from the transgender celebrities who have "come out" before him.

The Wachowski Brothers are famous for their box office hit movies such as The Matrix trilogy, but in 2012, they hit headlines for very different reasons when the eldest sibling, formerly known as Larry, made her first appearance as a woman after years of rumours.

It is believed Lana completed her gender reassignment in 2008 after wrapping up work on Speed Racer.
