They say imitation is the sincerest form of flattery!

Selena Gomez and her group of girlfriends posted a video of them doing a choreographed dance routine to Taylor Swift's "I Knew You Were Trouble" song, and we have to say we're mighty impressed with her dancing skills!

Justin Bieber's girlfriend is best buds with T-Swizzle, so we bet the country cutie didn't mind the Wizards of Waverly Place star putting her own spin on the tune!

We've always thought of the 20-year-old as sweet and innocent, but after seeing her moves in this video, we think of her more as a sex symbol!
