Nobody gets all up in stars’ business like Oprah Winfrey, and the media maven will continue her killer streak of stellar interviewing with the next installment of her revealing OWN series Oprah’s Next Chapter, on which R&B superstar Usher will publicly discuss his bitter custody battle for the first time.

“He said that he would talk to me and then he’s never gonna talk again about his marriage, the fact that his mother didn’t come to the [wedding], the fact that he’s gone through three years of a custody battle and now has primary custody of his own children … he talks about everything. No holds barred,” Oprah says in the episode preview.

She says he even reveals whether he makes love to his own music — something that’s a little TMI-ish for me, but whatever.

Check out the preview below. Oprah’s interview with Usher airs Sunday night, September 16, on the Oprah Winfrey Network.
