Actress Pamela Anderson has filed for divorce from her musician husband Kid Rock after less than four months of marriage, her publicist confirmed to TheShowbuzz.com. The couple were married July 29 on a yacht in St. Tropez. Then they tied the knot twice in August in a civil ceremony in Beverly Hills and at a honky tonk in Nashville. Rock, whose real name is Robert Ritchie, filed a separate divorce petition, within an hour of Anderson’s, early Monday. Anderson reported their separation date as Nov. 21; Ritchie said it was Nov. 26. Both cited irreconcilable differences as the reason.
