Moore Money for Demi

Earlier today, I told you about Rumer Willis' surprise singing performance at Teddy's in Hollywood. Now I have some dish on mom Demi Moore and stepdad Ashton Kutcher's Saturday night.

It wasn't exactly a romantic night for two, as others have reported. I am told the couple and about six others hit Los Angeles Chinese restaurant Genghis Cohen for dinner and then a show in the eatery's lounge.

And I'm happy to report Ms. Moore couldn't have been nicer. I'm told Moore didn't mind waiting at the bar for a table. My source reports she even apologized for showing up at such a busy time with no reservation.

After dinner, the group headed into the lounge for a music show. But things got a little tricky when Moore reached into her bag at the end of the night to pay for her posse's drinks after the show. "This is all I have," she said, according to my source. She apologized once again because she didn't have enough for a proper tip on the $43 bill. She apparently only had $45 in cash and no credit cards with her.

And nope, Kutcher apparently didn't have any money on him, either. But the waitress, I'm told, was cool about getting shortchanged. "She just said, 'Don't worry about it,' and let them go," the source said. "Demi was super apologetic."
