Caitlyn Jenner will once again sit down for an interview with Diane Sawyer on “20/20,” two years after she first came out on the show as a transgender.

According to ABC, the one-hour televised interview will air on April 21 and will see Jenner talking about her life after she transitioned from man to woman. In the teaser clip released by network (via People), Sawyer asks Jenner if she has doubts that she did the right thing. Jenner answers by saying that she’s certainly made some mistakes within the past two years. As of late, it’s still unclear what mistakes Jenner is referring to and whether or not it has to do with her transition.

In 2015, Jenner entrusted Sawyer with her coming out story and said that she’s always been confused with her gender identity even when she was just a child.

“I tried to explain it, because I’ve had all my kids sitting in that chair and I’ve tried to explain it this way. God’s looking down, making little Bruce and he says, ‘Okay, what are we gonna do with this one? Make him a smart kid, very determined.’ And then when he was just finishing he says, ‘Let’s wait a second.’ God looks down and chuckles a little bit and says, ‘Hey, let’s give him the soul of a female,’” she explained.

Jenner’s interview with Sawyer was also the last time she was referred to by her birth name, Bruce. It also coincides with the upcoming release of her memoir, “The Secrets of My Life,” which is on April 25, according to The Wrap.

The special “20/20” episode of Jenner will air on ABC on April 21 at 10 p.m. EST.
