“My whole life has been getting me ready for this.”

With that phrase, Bruce Jenner drops the biggest teaser yet about his much-anticipated interview with Diane Sawyer.

Bruce Jenner is set to talk with Diane Sawyer on a special edition of 20/20 called simply Bruce Jenner – The Interview. The episode airs April 24 at 9:00 PM on ABC.

Rumor about what Bruce Jenner might tell in this interview doesn’t range too wide. Tons of supposition about Jenner’s quest to embrace his femininity and transition to living as a woman has been tossed about for months. While the rest of the world seemed to already know that Bruce Jenner would drop the bomb any day now, his own mother was in the dark.

Last year, Esther had spoken to The Daily Mail about Bruce Jenner, particularly about rumors surrounding his divorce from Kris Jenner.

“I love him, no matter what,” Esther Jenner said. “There’s such raunchy publicity all the time. I don’t know. I’ve brought this up to him on the phone when we’ve talked and he says, ‘Mum ,you can’t believe this stuff,” he said, ‘You can’t pay any attention to this stuff,’ and I said, ‘Well I want to tell you one thing Bruce, I don’t care if what they’re putting out is true or false, it’s not going to change my love for you,’ and it’s true that’s exactly how I feel, but I don’t like it.”

Since then, Bruce Jenner has apparently sat his mommy down for a heart to heart.

“He said, ‘I want to be honest about my identity and I know this is coming out in the press,’ ” his mother says. “He started by saying, ‘We need to have a long, serious talk.’ ”

While some see Bruce Jenner — an Olympic gold medalist — revealing himself as transgender as one more step in society’s acceptance of transgender folks, others do not see the media circus around this as positive.

“When you make a spectacle out of guessing who is and isn’t transgender, it harms real transgender people just trying to go to school or work and trying to live their lives,” said Nick Adams, a spokesman for GLAAD who himself is transgender.
