Artists, musicians and bands gathered Sunday night at the Nokia Theatre in Los Angeles for the 2012 American Music Awards where Justin Bieber, Taylor Swift and Nicki Minaj were the biggest winners of the night.

The AMA show paid homage to the late Dick Clark, who produced the show before passing away this year. Sunday night's celebration for the award show's 40th anniversary included memorable clips from past shows the last four decades.

Justin Bieber was named favorite artist of the year, beating out Rihanna, Katy Perry, Maroon 5 and Drake for the AMA. Bieber, 18, brought his mother Pattie Malette on the stage to accept the award.

"This is my mom," he said. "She's little, but she's beautiful," thanking her for believing in him. Bieber also won the first award of the night for favorite pop/rock male artist.

"I want to say this is for all the haters who thought that I was just here for one or two years. I feel like I'm going to be here for a very long time," he said.

Stevie Wonder, who has won 11 AMAs in his career, performed a tribute to the late Dick Clark, who created the American Music Awards in 1973. Ryan Seacrest introduced the performance, which included a photo montage of Clark's career.

"This show, on its 40th anniversary, still reflects Dick's original vision," Seacrest said. "Bring the top artists on the planet together on an equal stage and then let the music speak for itself."

Singer Brandy also paid tribute to Whitney Houston who died this February before the Grammy Awards.
