Bruce Jenner speaks in new '20/20' promo

First we had shadows. Now Bruce Jenner is speaking.

Sort of.

ABC continues to tease the heck out of its upcoming mega-special with Bruce Jenner, who will speak for the first time about his "journey" to Diane Sawyer during a special edition of 20/20.

"My whole life has been getting me ready for this," says Jenner in the new promo. The two-hour special will air on Friday, April 24 at 9 p.m. ET.
