Taylor Swift looked more like Jem than Jackie O Sunday on the set of her new music video.

The 22-year-old "Red" singer rocked shoulder-length, tousled pink hair and cozied up to Reeve Carney while shooting "I Knew You Were Trouble" after the American Music Awards in L.A.

In addition to her punk rock 'do, Taylor wore cutoff denim shorts, a slouchy top and denim jacket.

Before she sassed up her blond locks, Taylor performed—and won Favorite Female Country Artist—at the American Music Awards. "Thank you so much for the AMA! You're unreal," she tweeted that night. "I went straight from the awards to a night video shoot. Long day but so worth it."

So worth it indeed, especially when we get to see this new, edgy T.Swift in action.
