Larry King has filed for divorce from Shawn Southwick, his seventh wife, after 13 years of marriage, TMZ has learned. In court papers submitted Wednesday afternoon in L.A. County Superior Court, King cites "irreconcilable differences" for wanting to end the marriage.

King's spokesperson Howard Rubenstein confirmed the filing to PEOPLE, saying "his major concern is the welfare of his children, and beyond that he's not going to comment about the divorce."
