ABC recently released the first trailer of Diane Sawyer's exclusive sit-down "20/20" interview with Bruce Jenner.

The cryptic trailer fails to show Bruce Jenner's face and doesn't specify what Jenner will talk about during the interview.

Instead, the trailer's narrator teases that Jenner will discuss, "the journey, the decisions, the future."

Hollywood Life reports that Jenner's two-hour "20/20" interview will include a formal sit-down with Diane Sawyer and a casual portion of the interview.

The interview is scheduled to air on Sunday, April 24 at 9 p.m. EST.

Although ABC has not specified what Jenner will discuss during the sit-down, Hollywood Life claims he will talk about his transition to become a woman.

"The interview is an emotional one for Bruce, and he 'breaks down' and 'cries' during the two-hour special," says a HollywoodLife source.

The source adds, "[Bruce] is going to reveal all of his struggles into transition and why it took so long for him to do it in the first place."

Although Jenner's children and ex-wife, Kris Jenner, have yet to publicly discuss his transition, celebrity fan Boy George has shown public support.

Boy George recently spoke to People about Jenner's transition and revealed that he is a "big fan" of Jenner and his decision.

"I absolutely applaud what he's doing and I think it's very brave. And it actually makes me quite emotional," he gushed, adding, "He has my 150 percent support in every way. I think that the whole transgender thing is the new frontier."

As he continues his transition to become a woman, Jenner has made the decision to distance himself from his Kardashian-Jenner family members.

RadarOnline claims that Jenner feels his brand has been diluted and controlled by Kris Jenner and her daughters.

In an attempt to fix his image, Jenner has allegedly hired publicist Alan Nierob who will guide him as he enters a new chapter in his life.
