America proved that nothing beats the Bieber Fever, as the teen singer dominated the American Music Awards on Sunday night by winning the show’s top award — Artist of the Year. His mom joined him onstage as he collected the trophy, beating out Rihanna, Maroon 5, Katy Perry and Drake. “I wanted to thank you for always believing in me,” Bieber said, looking at his mom.

Bieber then performed with singer Nicki Minaj. But another collaboration was the night’s most colourful performance - Korean rapper PSY and MC Hammer who grooved to the former’s hit number — Gangnam Style. As Bieber won his second award, he was kissed on the neck by actor Jenny McCarthy, who presented the award. “Wow. I feel violated right now,” he said, laughing.
