Rumer Willis knows it's all about the booty.
The daughter of Demi Moore and Bruce Willis showed some serious skin on Monday night's episode of "Dancing with the Stars" -- but it was her rear end that stole the show.
The actress hit the stage in a gold, sheer bodysuit that exposed her tight tummy and entire back, an outfit her mama would have been comfortable wearing in "Striptease."
Willis knocked her salsa routine with Val Chmerkovskiy out of the park, getting a 33/40 from the judges for their performance.

After the show, Rumer followed up her impressive dance number with an impressive shot of her derriere.
"Scout laRue and @buuski with the real star of #DWTS," she captioned the pic -- which shows sisters Scout and Tallulah posing with her pert posterior.
Right now, Rumer is one of the clear frontrunners of the season, something former contestant Candace Cameron opened up about while visiting the toofab studios. Check out her full interview below!
