The 15-second spot sparked interest in the two-hour special, showing glimpses of the back of Jenner’s head and a shadow shot of him speaking to Sawyer, wearing his long hair in a ponytail. “The journey. The decisions. The future. The Diane Sawyer exclusive,” teased the spot’s voiceover.

ABC confirmed earlier this month that the rumored interview with Jenner was a go, revealing that “Bruce Jenner – The Interview” would air on the network as a two-hour special starting at 9 p.m. EST on Friday, April 24.

The interview with Sawyer will be “far-ranging” and “exclusive,” according to ABC. No further details regarding the subject matter of the sit-down have been confirmed, though it is assumed that the former Olympian will address the rumors that he has begun physically transitioning to become a woman.

Jenner is also expected to address his purported transition on Keeping Up with the Kardashians and will apparently be shown coming out to his daughters and stepdaughters Kendall Jenner, Kylie Jenner, Kim Kardashian, Khloe Kardashian and Kourtney Kardashian – during the season’s finale.

After the current season of Keeping Up with the Kardashians wraps, it’s believed that Jenner will star in his own reality TV series on E! that will chart his transition. Following the fatal car accident on the Pacific Coast Highway that Jenner was involved in earlier this year, reports suggested that the docu-series had been halted or called off entirely. Though E! has not confirmed the project, it is still in the works, according to BuzzFeed.
