7 of 10: Taylor Swift performed her song '22' -- for the first time on live television -- at the Billboard Music Awards at the MGM Grand Garden Arena on Sunday, May 19, 2013 in Las Vegas.

The songstress' epic performance began with a backstage feature that showed her in her dressing room, playfully dancing out of it and engaging in a number of fun hijinks. While the performance ended with a creative mob scene that occurred center stage, the best part was perhaps in her acceptance speech for Top Artist.

"You are the longest and best relationship I've ever had," she playfully told the audience. (Photo/Albert Ferreira / ABC)
