You guys were blown away by Demi Lovato's awesome dancing skills at her Sweet 17 birthday party. (We were too!) Her choreographer and Camp Rock costar Jordan Francis just posted a video of them practicing before the big night.

Psst! It looks like their practicing in Demi's bedroom. It's like getting a peek into her world -- look at the piano in the corner!

Demi will be dancing a lot more in Camp Rock 2: The Final Jam -- are you excited for the flick?
