EMINEM

This year, Eminem warmed up the 2010 MTV Video Music Awards with his opening performance of "Not Afraid". The Slim Shady started spitting his verses from the backstage, which was arranged to look like a small stage before he came out to get more spotlights.

Just after he finished the last line from the chart topper, Rihanna appeared on the other side of the stage and brought another single from Eminem, "Love the Way You Lie". The Barbadian singer, who donned a fairy-like dress, walked slowly to join the rapper on the center stage right when the song was about to end.

The performance was ended with a huge ovation from the audience. Shortly after completing the gig, Rihanna tweeted, "SURPRISE!!! ....just had to do it guys!" while Eminem left the building to perform with Jay-Z at Yankee Stadium in the Big Apple.
