Eminem is writing a revenge song after actor Sacha Baron Cohen played a prank on him at the MTV Movie Awards, according to reports.

The rapper stormed out of the ceremony in Los Angeles on Sunday when Sacha, who was dressed as his homosexual character Bruno, was lowered onto his lap.

The audience at the Gibson Amphitheatre watched in horror as the semi-naked actor straddled Eminem's shoulders before he was removed by the rapper's security guards.

Although there is speculation the prank was set-up, the Daily Mirror claims Eminem is now writing a diss song against the star.

"Bruno's jokes are hilarious - well, the majority of people think so,” a source said. "But Em's not a person to be messed with.

“His blood was boiling after the gag, and he has vowed to get his own back. All the way home and well into the night Em was ranting to pals that it wasn't over."
