The competition was stiff, but 19-year-old Taylor Swift managed to beat out Michael Jackson, Lady Gaga, Kings of Leon, and Eminem for Artist of the Year at the 2009 American Music Awards. Swift also took home awards for favorite female pop/rock artist and best country album. Jermaine Jackson accepted favorite male soul/R&B artist, best soul/R&B and pop/rock album, and favorite pop/rock male awards on his brother Michael's behalf. Other winners included the Black Eyed Peas and Green Day. Sunday night's show included a few notable showstoppers. Rihanna took to the stage to perform a single from her new album Rated R. Lady Gaga put on one of the night's most memorable performances when she sat down to play a grand piano and it caught fire. Jennifer Lopez had a blooper moment when she slipped up on a dance move and landed on her bottom.
