Round 1: Taylor goes in first with a few sassy shoulder pops
But the girls won't go down without doing a few of their own
Round 2: You know Taylor means business when she raises her arm mid-song
But Taylor didn't count on them knowing that one too.
Round 3: Taylor goes all out, giving sassy looks to audience
And she even busts out this one. Your move Tegan and Sara
Looks like Taylor is going to take this one home unless they come out with something amazing
Winner: Tegan and Sara
