Future boyfriends best beware of Selena Gomez's moves!
Remember when Selena and her fiesty posse worked it out to Dustin Travella's Everybody Knows (Douchebag) to allegedly not-so-discreetly diss Justin Bieber??!
Well, apparently Selena did such a good job (DUH!) at throwing shade at the Bieby that Dustin recruited her for a cameo in the official music video.
And the pretty single lady DEFINITELY delivers the 'tude!
Ch-ch-check out the sassy vixen do her thang (above)!
