The exclusive is billed as a "far-ranging" two-hour special.
It's already one of the most talked about interviews of the year, and there's still a month to go before it hits TV.
Diane Sawyer sat down with Bruce Jenner back in February, but the ABC News anchor's interview just got an air date.
In a two-hour 20/20 special that will air on April 24 at 9 p.m. ET, Sawyer will speak to the former Olympian in a "far-ranging, exclusive" simply titled "Bruce Jenner – The Interview," according to an ABC release. No further details were made available about the show, and producers declined additional comment.

Speculation that Jenner, 65, has reportedly begun a gender transition has been widespread in media coverage, and the biggest question about Sawyer’s interview is whether or not that will be the main topic of discussion.
Sawyer is widely considered to be a world-class interviewer with relatable, compassionate appeal.
In contrast, questions about Jenner's changing appearance have led to jokes some found insensitive, including Jamie Foxx's comments at the iHeartRadio Music Awards. A story on the subject based on quotes attributed to Jenner's step-daughter, Kendall Jenner, was later retracted by Us Weekly, and a heavily photoshopped cover of the tabloid magazine In Touch provoked controversy earlier this year.

First reports that Jenner would sit down with Sawyer pre-dated the fatal car accident in which Jenner was involved on Feb. 7, so it is unclear whether that incident will be among the topics discussed. Jenner was not charged with any crime and cooperated with authorities following the accident, but it is possible that family of the woman who died may still file a wrongful death lawsuit against Jenner.
