The 2013 American Music Awards hosted by Pitbull airs tonight, and music's biggest stars are filling the Nokia Theatre in Los Angeles for a night of celebrating the best artists, songs, and albums of the year voted by you, the fans! Aside from the red carpet anticipation, here are three things we can't wait to see.

1. The PerformancesYou can count on seeing Justin Timberlake in all of his dapper glory onstage (hopefully he'll be dressed in a full Tom Ford ensemble), along with Katy Perry—who is opening the show with her hit song "Unconditionally,"a possible twerking Miley Cyrus, Macklemore & Ryan Lewis, newcomer Ariana Grande, and Lady Gaga.

2. Taylor's Big NightThe country singer is leading the female nominees with five—yes five—nominations, leaving us wondering if Swift will have a repeat of the Country Music Awards and leave the Nokia Theatre with an armful of statuettes. Plus, we can't wait to see what she will be wearing.

3. The Return of TLCThe ladies of TLC will be making their return to the American Music Awards with a special performance featuring a mysterious guest. Guess we'll have to watch to see.

Don't miss the 2013 American Music Awards tonight airing live from the Nokia Theatre in Los Angeles on ABC at 8/7c!
