Las Vegas — Another day, another domination for Taylor Swift: She was the red hot winner at the Billboard Music Awards.

Swift won eight of 11 awards, including top artist and top Billboard 200 album for “Red.” She told the crowd: “You are the longest and best relationship I ever had.”

She also had a colorful performance of her hit “22” — starting backstage and working her way to the main stage on the back of a bike with help from a dozen background dancers and a flurry of red balloons.

Justin Bieber also performed — twice — and was a multiple winner with three awards, including top male artist, social artist and the fan-voted milestone award, beating out Swift and Bruno Mars. When he accepted the latter, boos were heard, and he alluded to the tumultuous weeks he’s had in the public eye.

“I’m 19 years old; I think I’m doing a pretty good job. And basically from my heart, I really just want to say it should really be about the music, it should be about the craft that I’m making. This is not a gimmick,” he said. “I’m an artist and I should be taken seriously and all this other bull should not be spoken.”

Bieber performed with will.i.am and solo when he sang “Take You” in leather pants, a leather vest and a black shirt that had one sleeve, as blue laser lights beamed.

Miguel, too, had a show-stopping performance, though he seemed to kick a fan when he jumped over the crowd while singing his hit “Adorn.” The R&B singer appeared to have landed part of his body on one woman, who walked away, and kicked another, who held her head low.

Maroon 5 and fun. also were nominated for 11 awards and walked away with one win each in pre-telecast announcements. Gotye and Rihanna had the second-most wins with four awards each.

But the awards show, airing live from MGM Grand Garden Arena in Las Vegas on ABC, is less about the trophies — which reflect success on the Billboard charts — and more about the performances. Selena Gomez sang her seductive new hit, “Come & Get It,” while Chris Brown danced to his latest single, “Fine China,” though his voice began to crack during the performance. Duo Macklemore & Ryan Lewis performed their massive hit, “Thrift Shop,” which won top rap song. “First and foremost, gotta thank Goodwill, gotta thank Value Village,” Macklemore said to laughs.

Nicki Minaj won the first award in the live telecast for top rap artist, beating out Drake, Flo Rida, Pitbull and Psy.
