Bruce Jenner Filming Diane Sawyer Interview This Weekend & Will Air Much Sooner Than Expected

Bruce Jenner isn't wasting time now that the big transitioning secret is out! It was rumored that the Keeping Up With the Kardashians star was preparing to sit down with respected ABC journalist Diane Sawyer, and RadarOnline.com has learned that their on-camera talk is happening much sooner than first anticipated.

"Bruce will shoot an interview with Diane this weekend to discuss transitioning from male to female," a source exclusively confirms to RadarOnline.com. "Bruce realized that there's no longer any need to wait since the family knows and the public is pretty much aware of what's going on."

RadarOnline.com broke the news that Jenner's 88-year-old mom, Esther, is completely on board and supportive. "I just learned about Bruce's transition," she revealed. "Bruce filled me in, and we had a very long, long, long talk about it."

Confirming the news that Jenner, 65, will share on a documentary TV show what it's been like to change genders, Esther admitted she "did not know of" the inner struggle her child had gone through until recently. But, she insisted, she's "proud" of the Olympic champ who "deserves all the respect."
