Eminem Joins Rihanna Onstage for Surprise Duet (VIDEO)

Concertgoers at Rihanna’s Staples Center show in Los Angeles last night got a special surprise bonus, as rapper Eminem joined her onstage to perform their collaboration “Love the Way You Lie,” from Eminem’s recently released Recovery album.

The “My Name Is” rhymer and the “Rude Boy” chanteuse have been spending a lot of time together lately; this week the pair have been filming the video for the song in Los Angeles, under the direction of helmsman Joseph Kahn (who lensed Britney Spears’ “Toxic” video, among others). According to reports, former Transformers beauty Megan Fox and Lost actor Dominic Monaghan may also appear in the video for “some rather steamy sequences,” and Ri-Ri and Eminem perform together in front of a burning house.

Sounds like it will be epic. In the meantime, watch the music world’s newest power duo burn down the house at the Staples Center in the video below:
