Sexy isn't a word we usually use to describe Taylor Swift.

But the singer made us change our mind when she hit the stage at KIIS FM's 2012 Jingle Ball is a pair of high-waisted shorts.

And while they're not verging on hot pants territory, they're definitely more risque than what we've previously seen on the 22-year-old. Taylor paired them with a sparkly top and festive red flats, though we would've preferred to see a cute kitten heel instead.

Her ex Joe Jonas also performed with his brothers (Nick Jonas is looking pretty buff these days!), along with Ne-Yo, Ellie Goulding and One Republic's Ryan Tedder.
