Caught! Ashton Croons, but Demi Sits Out Karaoke

Demi Moore is too shy to perform—what gives?

Is Demi...losing it? Pretty pair Dem and her man, Ashton Kutcher, threw a holiday party for Ash's production company Katalyst at Geisha House on Thursday night.

"[Ashton] was doing karaoke," said the restaurant source. "It was pretty funny." So what was Moore up to then?

Demi was watching and she looked beautiful, her skin was glowing," while wearing a black sequin dress. But D.M. never got in the spotlight herself, allowing her hub-unit to steal all the attention while she kept quiet in her booth. Mrs. K was overheard saying, "I think I'll wait till everyone else has gone so I don't make a fool of myself."

Hey, Dem, you were once the highest paid actress ever, starring in tons of box-office hits, remember? And now you're too afraid to stand up and sing some corny song in front of a small group of friends? You certainly weren't like this with Bruce. Snap out of, and make another movie, wouldya?
