Watch Taylor Swift Challenge Tegan And Sara To The Best Dance Battle Ever

Who has the better dance moves? Watch what happened when Taylor challenged the sisters to a good ol' fashioned three round dance off.

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

Oh dear

Looks like Taylor is going to take this one home unless they come out with something amazing

Winner: Tegan and Sara
