Justin Bieber gave an emotional thank you to his mom, Pattie Mallette, who stood on stage with the pop star as he accepted Artist of the Year, his third award of the evening, at the culmination of the 40th annual American Music Awards Sunday in Los Angeles.
The Biebs, who brought his mother along as his date for the show, took home the first and the last award of the night, (Favorite Pop/Rock Album and Artist of the Year, respectively) as well as Favorite Pop/Rock Album for Believe.
Nipping at his heels with two wins this year, Nicki Minaj nabbed the awards for favorite rap/hip hop album (Pink Friday: Roman Reloaded) and favorite rap/hip hop artist.
The big-winning twosome also graced the stage to sing (once with each other) hits from their current albums. Taylor Swift, Christina Aguilera, No Doubt, Usher, Carly Rae Jepsen, Carrie Underwood, Kelly Clarkson, and Pink also made the night memorable with elaborate, theatrical performances.
Recently departed Dick Clark, who created the show forty years ago, was honored by Stevie Wonder with a variety of songs. Whitney Houston was also fondly remembered by singer Brandy, who introduced a brief tribute to the late artist.
