A well-received performance transformed into an embarrassing night at this year’s MTV Movie Awards for rapper Eminem.

The entertainer and his entourage left the annual show after an encounter with Borat star Sacha Baron Cohen on Sunday (May 31) night.

The actor, who was in character as the flamboyantly gay fashion reporter Bruno, flew into the Gibson Amphitheater on a wire in white wings to present the best male performance award to High School Musical star Zac Efron.

According to reports, Cohen was lowered into the audience after crashing into an overhead obstacle.

The comedian’s backside was exposed as he landed upside down onto Eminem’s lap, his bare behind in the rapper’s face.

“Are you serious? Are you fuckin’ serious? “Get the fuck off me!”" a visibly upset Eminem reportedly said as his entourage quickly came to get Cohen off the Detroit lyricist, who later stormed out of the building.

As he accepted his award, a confused Efron was taken aback by Cohen’s antics.

“That was really weird,” he said. “That’s the coolest way I’ve ever been invited up to accept one of these.”

The incident with Cohen came after Eminem performed two singles, “We Made You” and “Crack a Bottle,” from his latest album Relapse.

Hit the jump for the entire bizarre encounter.
