Well, well Lady Swifty! What elegance you've brought to the AMAs!
Taylor Swift had quite a few singles to choose from to perform tonight, but she went with her pretty-damn catchy jam, I Knew You Were Trouble to win the crowd over with!
And who doesn't love getting in trouble at a masquerade! Is Harry Styles under one of those masks?! ;)
Ch-ch-check out the video (above) to watch Taylor — who's already won tonight! — work her country booty to this great tune!
We will never ever ever every be sick of a catchy, Swifty tune!
