ABC aired a mysterious promo Thursday night of Bruce Jenner's interview with Diane Sawyer. The network just confirmed earlier this week that it will air an exclusive interview with the patriarch of the Kardashian clan, who is rumored to be undergoing a gender transition.

The commercial gives away very little info, but promises that Sawyer and Jenner will talk about his "journey, the decisions, the future," though it does not confirm any rumors. 

Jenner is seen speaking with Sawyer animatedly in the background, but the promo does not clearly show his face at any point. His long hair is pulled back into a ponytail and the shots of Jenner are either dark or fairly obscured. 

The two-hour interview will air on April 24.
