Baby got back! Rumer Willis goes for the gold in her tiny hot pants as she arrived at her rehearsal for Dancing with the Stars on Tuesday afternoon.

The 26-year-old star showed off a flashy pair of gold short shorts when she arrived at the dance studio in Hollywood on Tuesday. Rumer met up with her pro dancer Valentin Chmerkovskiy, who wore a much more toned down ensemble of black sweatpants and a clingy T-shirt.

All the working out seems to be paying off on the score board and and on her body. Rumer's bod' has never looked so toned!

On Monday night Bruce and Demi's daughter, who can also be seen singing and dancing in For The Record: Dear John Hughes , took to the ballroom and wowed the crowd when she did a dance as Ursula, the sea hag from The Little Mermaid, while her partner, Valentin, performed as an eel. The judges seemed impressed with the actress' moves and placed her on top of the leader board. Keep up the good work!
