Remember Striptease? It was actually a pretty sh*tty movie, but Demi Moore did some groundbreaking strip routines in it, and apparently she is all about teaching her craft to her daughter...in front of an audience!

Mothers and daughters like to shop together -- but pole dancing? That's what Striptease star Demi Moore, 47, and daughter Rumer Willis, 21, did for fun at a party at the Chateau Marmont in LA on Feb. 27. "There was a pole at the bash, and Demi thought it would be fun to show everyone she still has what it takes," a partygoer tells Life & Style. "Demi even spun around the pole upside down. It was incredible." Then it was Rumer's turn, as stepdad Ashton Kutcher and A-listers Jennifer Aniston and Leonardo DiCaprio, among others, looked on. "It was strange, but Demi encouraged Rumer to join her," says the partygoer. "Everyone was cheering, and Leo gave Ashton a high-five. Ashton put his arms around both Demi and Rumer and looked like the proudest man in the room."
