Life's Full of Laughter for Elizabeth Mitchell

They say laughter is the best medicine, but it is also the best aphrodisiac — at least for Elizabeth Mitchell. After three and a half years of marriage, the lost star tells OK! that her comedian-hubby Chris Soldevilla still tickles her funny bone.

"We laugh a lot," she tells OK! at the Hollywood Life Awards. "My husband's incredibly funny. He makes me laugh at myself because I tend to be incredibly serious. He's really cute. We have the same morals."

The couple keep the laughter going with their 2-year-old son Christopher Jr., a.k.a. "C.J.," who is "infuriating" and "amazing" all at once.

"It's the hardest thing I've ever done and it's the best thing," she says. "He makes your heart bigger and your head bigger. That can't be a bad thing."

While motherhood is "lovely," the 37-year-old isn't in a rush to expand her family.

"It's a thought. We'll see. It could happen."
