Sean Penn's wife seeks divorce

Robin Wright and her husband Sean Penn are ending their 13-year marriage.

People magazine said Wright filed for divorce from Penn on August 12 in Marin County, California.

The magazine says Wright and Penn, who have had a tumultuous relationship, have agreed to share custody of their 16-year-old son, Hopper Jack.

Court papers cite “irreconcilable differences” for the split.

The couple married in April 1996. The Penns have twice before filed for divorce or separation, only to dismiss their petition a short time later.

Penn won an Oscar for his role in Milk at the Academy Awards in February but did not thank his wife in his acceptance speech.
