Taylor Swift rocked a white lace top and high-waisted shorts while performing her sassy, make-fun-of-your-exes, have-breakfast-at-midnight and fall-in-love-with-strangers song '22' for a good cause. She looked virginal, but had a sparkle in her eye.

T. Swizzle performed the carefree and fun song at the 'Let's Dance for Comic Relief' event in the U.K. It's fitting that she performed a song about dancing like you're 22 at an event with the word "dance" in its name! Swift sure busted a move like she was having a good time.

So while she is no longer with One Direction's Harry Styles, and hasn't been for months, they remain connected since they have this particular cause in common. Both have supported the charity with performances, songs and more.
