Pharrell was not won over by Taylor Swift's in-seat dancing at the Grammys last night.

He gave her little performance some serious side eye, and the Vine of his disapproval has over 3 million loops.

Maybe he's contemplating if she's secretly sad she didn't win any Grammys. Or maybe he was just wondering why her dress straps look like she's carrying a backpack, but there is no backpack. Confusing!
