Tonight at the 2011 American Music Awards, a bevy of artists hit the stage for some amazing performances. In these performance pictures from the American Music Awards, see pop stars like Nicki Minaj and David Guetta -- who opened up the show with 'Turn Me On' and 'Super Bass' -- as they performed on Nov. 20 for the masses at the Nokia Theatre in Los Angeles, Calif.

Justin Bieber also performed at the show, singing his Christmas song 'Mistletoe,' while Kelly Clarkson donned a sexy red gown for her live rendition of 'Mr. Know It All.' Jennifer Lopez stripped down during her 'Papi' and 'On the Floor' performances, revealing a nude body suit with strategically-placed jewels at the end of her dance-filled show. She even dropped it low for Pitbull, who also performed with J. Lo's ex-husband Marc Anthony (we wonder if he and Lopez had any awkward run-ins at the show).

Other performers included Katy Perry, who put on a very pink performance of 'The One That Got Away.' Mary J. Blige and Drake performed new tracks, as did, who performed some fresh solo songs alongside Lopez and a video projection of Mick Jagger. Daughtry delivered a much-needed dose of rock, while Maroon 5 and Christina Aguilera got the crowd groovin' to 'Moves Like Jagger.' The most entertaining performance of the night came from LMFAO, who closed out the show with a full-blown party as they shuffled with The Biebs to 'Party Rock Anthem' and wiggled it out with The Hoff during 'Sexy and I Know It.'
