We know our headline says Katy Perry but technically, technically it's Katy's uber-geek alter-ego Kathy Beth Terry who's having a dance. We know she has terrible braces and permed hair but we still want to BE Kathy Beth Terry especially with her hot moves.
Just Dance are sponsoring Katy Perry's California Dreams UK tour which is running all through October until Novemember. Hence Katy Perry is busting her moves on the new Just Dance 3 game on Kinect™ for Xbox 360® and Nintendo Wii. Have a watch of Katy and all her fans singing along to Firework... What do you make of Katy's dancing? Loving her as always? Comments below please!
