In a three-hour show heavy on performances, chart staples LMFAO helped kicked the show off with a typically hyped performance of their inescapable party anthems that featured a cabbage-patching teddy bear and zebra and more animal prints than a Flintstones family reunion. Justin Bieber was the night’s first winner, taking the Top Social Artist award for his huge online presence. The singer swaggered up to the stage and, in an uncharacteristically emotional moment, said, “I just want to say how much of a blessing it’s been … the past three or four years, growing up in front of everybody. … I want to thank all my fans, because the Internet is where I got my start, and all my fans have helped me get to this position.” Co-host Julie Bowen took a moment out of the program early on to pay tribute to late Bee Gees member Robin Gibb , who died earlier in the day Sunday after a long battle with cancer. The night also featured a touching tribute to recently passed disco queen Donna Summer by Natasha Bedingfield and a segment devoted to music legend Whitney Houston with a medley of her indelible hits performed by John Legend and Jordin Sparks.

The ladies had a great night, as Taylor Swift was honored with the Billboard Woman of the Year award, acknowledging her stadium full of impressive credits, including a place as the only woman in music history to score three #1 albums in a row, each of which has sold more than 5 million copies. Swift, 22, dressed in a flowing red evening gown and ever gracious, thanked her legions of fans, saying, “I just love you so much, I’m just so humbled and honored by this.” As Miley Cyrus noted, you’re only new to the game once, so it was fitting that red-hot rapper Wiz Khalifa best the competition for the Top New Artist trophy. “I’m up here shakin’, man,” the rapper admitted as he thanked his whole crew and label family, as well as his “beautiful fianc
