Eminem has been tapped to perform at the 2009 MTV Movie Awards, airing live from the Gibson Amphitheatre in Universal City, California, on Sunday, May 31, at 9 p.m. ET. Andy Samberg will host.

Em's performance will come just a few days after the May 19 release of his much-anticipated new album, Relapse, (featuring the single and video "We Made You," which premiered on MTV last week).

Viewers can vote online and on their mobile phones to select the nominees for the 18th annual Movie Awards. On May 4, the nominees will officially be announced, and viewers will once again be able to vote for their favorites online and from their mobile phones. The second round of voting closes on May 18, with the exception of the Best Movie category, which will remain open throughout the show.

Eminem won't be the only performer taking the stage at the Movie Awards — last year, Coldplay and the Pussycat Dolls had the honors — but we're not ready to reveal who will be joining him on May 31 just yet.

Additional performers and presenters will be announced in the coming weeks.
