Justin Bieber Owns American Music Awards; Taylor Swift, Rihanna, Eminem Also Win

Teen superstar becomes the youngest artist ever to win the Artist of the Year Award at the American Music Awards Sunday night.

Justin Bieber wasn't kidding calling his album My World 2.0.

The 16-year-old crooner owned Sunday night's American Music Awards, beating out Lady Gaga, Katy Perry, Eminem and Ke$ha for the coveted Artist of the Year trophy. 

And that was just one of the four wins for the teen heartthrob...

Bieber, who became the youngest artist ever to win the AMA Artist of the Year award, raked in the most awards of the night, also grabbing nods for the T-Mobile Breakthrough Artist of the Year, Favorite Male Pop/Rock Artist and Favorite Album.

Rihanna opened with a medley of hits, singing "Love the Way You Lie (Part 2)", "What's My Name" and "Only Girl (In the World) in fishnets and a barely-there sarong. She took home the trophy for Soul/R&B Female Artist, but before Rihanna's name could be announced, rapper Nicki Minaj took a moment to give a shout-out her upcoming album...though we won't.

Miley Cyrus belted out "Forgiveness and Love" on a candlelit set, a move she'd clued E! News to earlier in the week. 

The Black Eyed Peas later popped out of Day-Glo boxes for a futuristic performance for their new hit "This Time (The Dirty Bit)". The group trumped Lady Antebellum and Train, taking home the Favorite Pop/Rock Band, Duo or Group nod. 

And not one to take after baby bumpin' performers of the past (à la Alicia Keys atop a piano at the BET Awards) a pregnant Pink performed "Raise Your Glass," though she did ditch her aerial acrobatics to keep both feet on the ground.
