Locklear & Sambora: Over!

ET has confirmed the surprising news that after more than 11 years of marriage, HEATHER LOCKLEAR, 44, and her rocker husband, RICHIE SAMBORA, 46, are calling it quits. In court papers filed today, Locklear cites "irreconcilable differences" as the reason for the split.

"Heather Locklear has filed for divorce from Richie Sambora," according to her publicist. "This is a private matter and there will be no further comment at this time."

The "Melrose Place" star and BON JOVI guitarist have one child, 8-year-old AVA ELIZABETH. Locklear was previously married to another rocker, TOMMY LEE.

Just last June on the red carpet at 'The Perfect Man' premiere, Sambora told our KEVIN FRAZIER what made Locklear so perfect for him: "Just look at her, I got the prettiest girl in the place everywhere I go."
