Bieber wins Artist of the Year

America proved its Bieber Fever was strong: The teen singer dominated the American Music Awards on Sunday night.

Bieber’s wins included the show’s top award, artist of the year.

The singer’s mom joined him onstage as he collected the top award.

He looked to his mom: “I wanted to thank you for always believing in me.”

He said it’s “hard growing up with everyone watching me” and asked that people continue to believe in him.

The 18-year-old also won favorite pop/rock album for “Believe” and male artist.

He performed two songs at the award show, one stripped and another upbeat with Nicki Minaj. As Bieber won his second award, he was kissed on the neck by Jenny McCarthy, who presented the award.

He earlier 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 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, also thanking his mom, manager, family and his “beautiful, beautiful fans.”

He gave a stripped down, acoustic performance of “As Long As You Love Me,” sitting down as someone played the guitar. He transitioned to the dance-heavy “Beauty and a Beat,” where Minaj joined him onstage, grinding with the teen for a few seconds.

Minaj repeated her AMAs wins from last year, picking up trophies for favorite rap/hip-hop artists 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.” The scene was ghostly and snowy, as a choir — also in white — joined her onstage. One background singer stole the performance, belting semi-high notes as Minaj looked on.

Carly Rae Jepsen, who performed early in the night, won favorite new artist.
