Chaz Bono rocked it out last night on the first episode of Season 13's Dancing With The Stars.

Sonny and Cher's child danced the cha-cha with professional partner Lacey Schwimmer and wow, he's got rhythm!

After the performance to the song "Dancing In The Street," DWTS judge Carrie-Ann Inaba said the following:

    “I think people have been waiting all night to see you, Chaz, and you do not disappoint! You can dance! You had great footwork. You’ve got so much joy. You light up this room."

You go, boy! On the other side of the spectrum ... George Clooney's ex Elisabetta Canalis. Yikes! Girlfriend needs to practice BIG TIME. Watch her dancing debut below.
