Ariana Grande, Taylor Swift, & 1D Perform At Tonight's American Music Awards

Whatever you were planning to do tonight, cancel it. Oh, wait. You were planning on watching the American Music Awards? Never mind then.
Airing live on ABC this evening, the awards show is bringing out the big guns and adding fuel to some romance rumors in the process. Taylor Swift and One Direction on the same stage? Major. Lil Wayne performing with new flame Christina Milian? Love it.
Hosted by Pitbull (yes, you read that right), the show has also recruited Lorde, Garth Brooks, Wyclef, Imagine Dragons, MAGIC!, Sam Smith, Iggy Azalea, Jennifer Lopez, and Nicki Minaj. Basically, that's just the tip of the iceberg. Keep reading to see who else is performing, what they could win, and why you should watch. You can always DVR Homeland.
