Rapper Eminem has reportedly admitted that everything about the outrageous bare-buttock incident involving provocative comedian Sacha Baron Cohen at Sunday's irreverent MTV Movie Awards was completely staged.

In an interview with the website RapRadar.com, Eminem said the stunt was all rehearsed, including his apparent disgust and angry exit from the award show.

"After the ceremony, I went back to my hotel and laughed uncontrollably for about three hours. Especially after I saw it on air," Eminem told the website.

"I'm thrilled that we pulled this off better than we rehearsed it. It had so many people going 'nuts,' so to speak. Everyone was blowing me up about it."

During the live show Sunday night, Cohen emerged in a harness high above the Los Angeles auditorium in character as his gay fashionista Bruno and dressed in a feathery, winged outfit with his buttocks largely exposed.

He was subsequently lowered upside-down into the lap of Eminem, with the actor's nearly naked bottom planted in the face of the visibly disgusted rapper — whose entourage roughly removed Cohen before Eminem stormed out, cursing.

Eminem said Cohen called him when he was in Europe with an idea to do something outrageous at the Movie Awards.

"I'm a big fan of his work, so I agreed to get involved with the gag."

Scott Aukerman, one of the ceremony's comedy writers, posted on his blog earlier this week that the incident was "all anyone wants to talk about."

"So let's get it out of the way," he wrote. "They rehearsed it at dress [rehearsal] and yes, it went as far as it did on the live show then."

The web posting has since been removed. MTV officials declined to comment.

The incident was the most memorable highlight of the two-hour, celebrity-heavy event and was subsequently streamed more than 800,000 times on the MTV.com website during the 24 hours following the Sunday night show, MTV said.
