Moon Unit Zappa, Paul Doucette divorcing after 9 years

moon-unit-zappa.jpgAdd one more couple to the list of 2011's celebrity splits. Moon Unit Zappa, the daughter of late rocker Frank Zappa, plans to divorce her husband of nine-and-a-half years, Matchbox 20 guitarist Paul Doucette.

According to TMZ, Zappa filed papers late last week ahead of the New Year's weekend. She and Doucette married in June 2002 and have one daughter, seven-year-old Mathilda Plum.

At age 14, Moon sang lead vocals on her father's single, "Valley Girl," which, like, totally launched a massive pop cultural trend with terms like "gag me with a spoon." Yes, really. It was the '80s.

Zappa has worked as a stand-up comic, a writer and an actress. She's most recently been seen on episodes of "How I Met Your Mother" and "Gray's Anatomy."
