Demi Moore needed a good laugh. And on Oct. 20 she got just that while taking in Sarah Silverman’s stand-up routine at the L.A. comedy club Largo. “She seemed happy,” says an observer. “It looked like she was having a good time.”

Good times have been in short supply. Since reports surfaced that her husband of six years, Ashton Kutcher, 33, cheated on her, Moore, 48, has been anxious, unable to sleep and losing weight, say several close sources. Friends, along with Moore’s daughters Rumer, 23, Scout, 20, Tallulah, 17, and ex-husband Bruce Willis, 56, “are worried,” says an insider. “Demi has demons to battle. She is finding it hard to stay level.”

Kutcher is also feeling the stress. On Oct. 19, the actor, not wearing his wedding ring, posted a rambling video on truthfulness. “They’re trying to see what can be salvaged,” says the insider. The pair are undergoing Kabbalah counseling, which emphasizes forgiveness. Says a Kabbalah source: “The woman must hold things together.”

Moore seems to be trying. Two days after Kutcher posted his video, she visited him on the set of Two and a Half Men. “They still love each other,” says the source. “They’re figuring out how to proceed.”
