Taylor Swift has changed up her look before, but never like this! The singer was photographed filming the music video for her new single I Knew You Were Trouble on Sunday, and it looks like she's showing off a much edgier side for this one!

Instead of her normally polished look, Taylor opts for shorter, messy hair (tinted with pink), along with a leather jacket, cut-off jean shorts over black tights, and black converse sneakers. Don't expect this to become an everyday look for the singer, though! In the song, Taylor relives a relationship she went through with, despite initially knowing it would end badly, so her look is likely just mirroring her lapse of judgement and stint with a "bad boy."

Taylor's co-star for the vid is Reeve Carney, who stars in Spider-Man: Turn Off the Dark on Broadway and is even better known for dating Twilight star Ashley Greene (although they broke up this fall).

Although she's cozying up to Reeve on set, Taylor is rumored to be dating One Direction's Harry Styles in real life. This, of course, comes right on the tail of her break-up with Connor Kennedy last month. Doesn't the girl just want to take a break from dating for a while?!

What do you think of Taylor choosing I Knew You Were Trouble as the next single?!
