The 38th annual American Music Awards were announced in Los Angeles on Sunday. And 16-year-old teen heartthrob, Justin Bieber, just couldn't lose at his AMA debut.

 

Justin Bieber's first American Music Awards was perfection. He went four-for-four on Sunday night, capturing every award he was nominated for. That included the top award of the night, favorite artist. He beat a list that featured veterans Eminem and Usher, as well as Katy Perry and Lady Gaga.

Bieber became the youngest person to ever win the trophy. He also won favorite pop/rock album, favorite pop/rock male, and the show's breakthrough artist award.

Bieber also performed his song "Pray" with a choir backing him.

Eminem, along with Lady Antebellum, had been the leading nominee with five awards. He didn't come up empty handed though, winning two, along with Usher, who also nabbed a pair. Lady Antebellum took home one.

The Black Eyed Peas, winners for favorite pop/rock band, gave a levitating performance, singing from boxes atop the stage during part of their performance of their new single, "The Time."

Taylor Swift, last year's artist of the year, clinched the title of Country Female Artist and performed her new single, "Back to December."

An exuberant Rihanna danced onstage to receive her award -- favorite soul/R&B female. With her hair dyed a ruby red, Rihanna performed a medley of songs from her just released album "Loud," including the No. 1 hit "What's My Name," wearing a bustier and what seemed like a scarf wrapped around her backside.

The ceremony at the Nokia Theatre in Los Angeles was as much a showcase for acts with new albums as it was a celebration of the biggest achievers of 2010.

Yet some of the prime-time performances were given to acts who weren't nominated, but had albums to promote. Diddy's latest incarnation with the group Diddy-Dirty Money sang material from their upcoming album.

Kid Rock gave a stirring, acoustic performance of "Times Like These," his song lifting up his hometown of Detroit during its recent economic struggles.

Katy Perry had the evening's most explosive performance as pyrotechnics accentuated the performance of her latest song, "Firework."
