After spending the last few weeks vacationing in Hawaii with her superstar boyfriend, Justin Bieber, and even making a pit stop in Canada to meet his family, Selena Gomez made an appearance at the MTV Movie Awards in Los Angeles on Sunday evening.

The adorable actress/singer wasn't shy about showing off her tanned legs, strutting her stuff in a white Giambattista Valli minidress. The 18-year-old star will be cheering for Bieber, who is nominated for Best Jaw Dropping Moment for his concert documentary 'Never Say Never.'

Bieber was thought to be absent from the show, but the little scallywag popped out from backstage after winning the Jaw Dropping award.
