Best and Worst Moments - 2009 American Music Awards

With appearances from Rihanna, Jay-Z, Whitney Houston and more, the AMAs were all about the performances -- and thanks to Lady Gaga, some of them were quite literally on fire. Check out the best and worst moments from this year's gong fest.

Best Recovery - We were enjoying Jennifer Lopez's fight-themed performance of "Louboutins," until she attempted to walk on the backs of her backup dancers and ended up falling on her butt. Always the professional, she quickly jumped up and played it off, making us dig the performance even more.
