what video did taylor swift dance to justin biebers song??? i havent seen it and i really want to! someone plzz give me the link

She didn't dance, she sang it:

"Taylor made a video singing my song one time on YouTube," pop music's newest 15-year-old singing sensation tells us. "And so I twittered her. She was twittering me back and we got to hang out."

She sang One Time. Look it up on Youtube, :)

-Just another crazed Justin Bieber fan.

To the other commentor, NO. She DEFINITELY danced to it, not sang it.
Anywhoo, here's the vid.
