Lady Gaga, and scheduled performers Katy Perry and Taylor Swift, are among the top nominees of the night. But despite the awards show's name, it's actually a non-American who leads the pack with the most nods. Brit singing sensation Adele may very well be this year's big winner. But don't expect the 'Someone Like You' singer to take the stage -- she'll be recovering from her recent throat surgery.
Speaking of taking the stage, it looks like this year's show is all about the superstar lineup of performers. Nicki Minaj and David Guetta will get the party started with 'Where Them Girls At,' while Maroon 5 and Christina Aguilera are slated to perform their hit 'Moves Like Jagger.' Maroon's Adam Levine will be performing double duty at the show, when he hits the stage again to sing with Gym Class Heroes' on 'Stereo Hearts.'
Ludacris is also slated to join Enrique Iglesias to heat things up with 'Tonight (I'm Lovin' You),' while Pitbull, Lil Jon and Marc Anthony will perform 'Rain Over Me.' Speaking of Marc Anthony, be sure to look out for a potentially awkward run-in with his soon-to-be-ex-wife Jennifer Lopez, who will also be in attendance. Also, keep your eyes peeled for a Rihanna/Chris Brown interaction -- they'll both be there, too!
Kelly Clarkson, Justin Bieber, the Band Perry, OneRepublic, Mary J. Blige, LMFAO and Drake round out the roster of performers, making us wonder when there will even be time to present any of the awards!
