2012 American Music Awards: Performances / by

As last night,, some of the biggest names in music took to the stage to perform on the American Music Awards which took place at the Nokia Theater in downtown Los Angeles. We saw performances from Nicki Minaj, Chris Brown, Justin Bieber, Usher and more.

There was even a surprise guest that shocked viewers. MC Hammer made his way back onto the stage as he partnered with PSY and mashed up the hits "Gangnam Style" and "2 Legit 2 Quit" and in my opinion was the best performance of the night.  You can check out all of the performances below.
