This is soooo the kind of stuff we like to see from some of our fave celebs!
But leave it to Demi Lovato, Kelly Rowland and Paulina Rubio to pull in Simon Cowell to perform (You Better) Ask Me to Dance - a song written by two contestants who didn't impress the judges enough. Although, it seems their song certainly did inspire them!
And with some MA-JOR Kelly booty shakin' going on, this vid is beyond! Not to mention, someone's ex makes an inneresting appearance…especially considering he's got a baby momma!
Ch-ch-check it out (above)!
