When Katy Perry tweeted, "@taylorswift13 CAN'T. WAIT. FOR. DANCE. PARTY," we thought, 'What on earth was she talking about?!' Turns out she had a little duet up her sleeve!
Taylor Swift was performing at the Staples Center in Los Angeles last night when she started to do a cover of Katy's hit single "Hot N Cold." The crowd was quickly greeted by Katy, who joined Taylor on stage to perform the tune together.
Check out the duet here:
