Larry King files for divorce from wife No. 7

LOS ANGELES -- Larry King has filed for divorce from his seventh wife, court filings show.

The 76-year-old host of CNN's "Larry King Live" filed Wednesday to end the couple's nearly 13-year marriage, citing "irreconcilable differences." He married Shawn Southwick-King in a hospital room in 1997 shortly before surgery to clear a clogged blood vessel.

The couple have two sons, ages 11 and 9. King is seeking joint custody of the boys. He is also asking a court not to award Southwick-King, 50, any spousal support.

"His major concern is the welfare of his children," said Howard Rubenstein, a spokesman for King.

Rubenstein said the talk-show host would not comment further on the divorce.

The filing was first reported by celebrity Web site TMZ.com.
