The Queen of Pop revealed that she once kissed the King of Pop on Wednesday's episode of The Late Late Show with James Corden.

Madonna appeared in the popular Carpool Karaoke series on Dec. 7 and she and the late night host drove through New York City. She said that she doesn’t like riding in a car without music so Corden put some tunes on for her. While singing "Vogue" Madonna did some leg splits and extended her leg vertically to the car's ceiling. She then twerked in the passenger seat to "Bitch I’m Madonna."

During the ride, Madge revealed that she once French-kissed Michael Jackson.

“Baby, I’ve been around. Yeah, tongue-in-mouth kissing,” she said. "He’s a little bit shy. However, he was a willing accomplice. I did get him to, sort of, loosen up with a glass of Chardonnay. And it did wonders. It worked wonders.”

The singer also said that she wants a man who has a sense of humor and can understand her sense of humor. She also said her life is pretty predictable because she doesn’t smoke, drink or party and so she’s square.

Madonna’s Rebel Heart tour film premieres Dec. 9 on Showtime.
