Friday is the D-day. Bruce Jenner is finally opening up about transitioning into a woman in an interview with Diane Sawyer.

In the latest promo released today, Bruce said: “It’s going to be an emotional roller coaster, but somehow I’m gonna get through it.”

“I wanna know how this story ends, you know? How does my story end?,” the Olympian posed a cryptic question.

The much anticipated interview between Bruce Jenner and Diane Sawyer will air tomorrow on ABC at 9pm EST.
