Taylor Swift was among the winners Sunday night at the first-ever YouTube Music Awards, held at Pier 36 in New York City.
Taylor picked up the YouTube Phenomenon prize for inspiring the biggest number of fan responses.
The Video of the Year category was stacked with pop stars like Lady Gaga , but they all lost to the South Korean group Girls' Generation and their "I Got a Boy" clip.
Though she wasn't a winner, Gaga still made her mark on the ceremony by performing one of her new ARTPOP tracks, "Dope," live for the first time. In fact, she arrived on the red carpet with the same unusual look -- complete with grills -- that is seen in her recently-revealed artwork for "Dope."
Avicii ; alternative rockers Arcade Fire ; rappers Eminem , M.I.A ., Earl Sweatshirt and Tyler, the Creator ; and the band Walk Off the Earth were also on the bill.
Actor Jason Schwartzman and comedian/musician Reggie Watts hosted the YouTube Music Awards, which was streamed live on YouTube.
