Greta Gerwig dances away to Arcade Fire during YouTube Music Awards

(UPI) -- The first ever YouTube Music Awards Sunday featured "live" music videos from Lady Gaga, Eminem, Tyler the Creator and others, but perhaps the most eye-catching video of the night was Arcade Fire's opening number with Greta Gerwig.

In the clip, the 30-year-old actress dances like nobody is watching to the tune of Arcade Fire's Afterlife.

Winners of the night included Eminem who won "Artist of the Year," Macklemore & Ryan Lewis who won "YouTube Breakthrough." Taylor Swift's I Knew You Were Trouble took the "YouTube Phenomenon" prize.

The live show was directed by John Gonzalez. You can check out more videos from that night on the award show's YouTube page.
