OSCAR winner Sean Penn and his actress wife Robin Wright Penn have filed for divorce for a third time, according to US reports.
People magazine reported Wright Penn filed the petition last week, citing â€œirreconcilable differencesâ€.
The couple, who wed in 1996, have twice begun divorce proceedings â€” in December 2007 and April 2009 â€” only to withdraw their petitions shortly after.
They have two children, daughter Dylan Francis, 18, and son Hopper Jack, 16.
People reported the couple have agreed to share custody of their son.Â Wright Penn first filed for divorce in 2007 before legal proceedings were dismissed four months later.Â Penn petitioned again in April earlier this year, only to withdraw the request less than a month later.
Penn won an Oscar for his role in Milk at the Academy Awards in February, but eyebrows were raised when he did not thank his wife in his acceptance speech.
The 48-year-old was previously married to pop star Madonna, with whom he co-starred in 1986 film Shanghai Surprise.
Wright Pennâ€™s movies include The Princess Bride, Forrest Gump and recent thriller State of Play.
The actress, 42, will soon be seen opposite Jim Carrey in a computer-animated version of A Christmas Carol.
