Britney Working Hard In The Dance Studio

Britney's choreographer, Brian Friedman, Tweeted fans saying Britney is working her butt off in the dance studio.

Maybe for a possible GRAMMY performance?!

Says the dancer:


Great rehearsal today with @britneyspears for HIAM! Sweating like old times... Get ready to Gag!

Can't wait!

UPDATE: Brian said to MTV the music video is going to be a dance video! He also showed Britney a sick routine which "overwhelmed her," but has since learned and is killing it!
