MTV - MTV tracked down this fan captured YouTube video of Taylor Swift rocking out at Ed Sheeran’s NYC concert last weekend. 

The “I Knew You Were Trouble” singer puts her dance moves in full swing. 

Tay’s signature swaying, leaning, and hair flipping are all present, but it looks like she’s added a couple of new moves to her routine. 

If only Taylor’s brother Austin ( he’s the kid just hanging out on her right side ) would join in! Honestly, is there anything better than T Swift’s audience- member dance moves?
