We already knew Bruce Jenner was going to share the details of his male to female transition with a news outlet, but now it's been confirmed that the reality star will sit down with Diane Sawyer to discuss his story.

"Diane has always been very supportive of the LGBT community," an insider tells Us Weekly. "She has been honored by GLAAD." The interview will air in May, and a source tells Page Six that Bruce will start filming the interview this week. And not only that, but the transition will be the focus of Bruce's new series on E!, along with Keeping Up With the Kardashians. "The world will see his full transformation," a source tells Us. "It's a docuseries featuring the Jenner family talking about Bruce 'coming out.'"

Last week Kim Kardashian hinted that something was up when she said Bruce would share his story when he was ready, calling his changes a "journey." When asked about a recent photo that Khloe posted of all the girls with Bruce, Kim added, "That was not like a secret message like, 'We support Bruce.' Of course we support Bruce 100 percent. He's our dad so we support him no matter what, and I think when the time is right, he'll talk about whatever he wants to talk about."

We can't wait to hear it! But now that the cat's out of the bag, can someone in the Kardashian family get Bruce some sexier threads? He's doing great with the lips and hair, but his baggy jeans aren't the best look...
