Teen singer Justin Bieber dominated the American Music Awards on Sunday night, winning the show's top award, artist of the year, and two others.
The singer's mom joined him onstage as he told her: "I wanted to thank you for always believing in me."
He said it's "hard growing up with everyone watching me" and gave a shout-out to those who didn't think he would last on the music scene.
"I want to say this is for all the haters who thought 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.
As Bieber won his second award, he was kissed on the neck by actress/activist and former Playboy model Jenny McCarthy, who presented the award.
"Wow. I feel violated right now," he said, laughing.
He gave a stripped-down, acoustic performance of "As Long As You Love Me" and then transitioned to the dance-heavy "Beauty and a Beat," joined by Nicki Minaj, who received two awards and grinded with the teen for a few seconds. Minaj won favorite rap/hip-hop artist and album for "Pink Friday: Roman Reloaded." She was in an all-white get-up, including fur coat and pink hair, when she performed her new song, "Freedom."
Bieber's red and black outfit seemed to be the night's theme, as Taylor Swift and Usher wore similar ensembles.
Swift won her fifth consecutive award for favorite country female artist. Luke Bryan won favorite country male artist and Lady Antebellum favorite country group.
Carly Rae Jepsen, who performed early in the night, won favorite new artist.
Party girl Ke$ha performed her hit single "Die Young." Kelly Clarkson also hit the stage, making a nod to her "American Idol" roots with a number on her dress and three judges looking on as she sang "Miss Independent." Fellow "Idol" winner Carrie Underwood won best country album and also performed "Two Black Cadillacs."
American Music Awards nominees were selected based on sales and airplay, and fans chose the winners by voting online. The 40th-anniversary broadcast from the Nokia Theater in Los Angeles featured a tribute to Dick Clark, its creator.
