Wonder if Demi Moore is cool with this?

Rumer Willis and Demi's ex Ashton Kutcher hit the town in Hollywood Tuesday night for some late-night partying at The Sayers Club.

A clean-shaven Ashton, wearing black pants and his best Christmas sweater, left the club with some buddies. As for Rumer, the 23-year-old actress left holding on to the arm of a cute male friend.

With mom Demi Moore fresh out of treatment, is it appropriate for her ex to be partying with his stepdaughter? You be the judge.
