DEMI MOORE POLE DANCES WITH DAUGHTER

This is what happens when your mom's a cougar.

Recently at a party in L-A, Demi Moore showed she still has her Striptease moves by getting busy on a stripper pole -- she even "spun around the pole upside down," one witness said. But things got bizarre when, according to the New York Daily News, Demi's 21-year-old daughter Rumer Willis stepped into her mom's stilettos and took a turn on the pole, as stepdad Ashton Kutcher watched. The source added, "It was strange, but Demi encouraged Rumer to join her... Ashton put his arms around both Demi and Rumer and looked like the proudest man in the room."
