LOS ANGELES, California (CNN) -- Mel Gibson's wife of 28 years filed for divorce from the actor last week, citing "irreconcilable differences."
Mel Gibson and his wife, Robyn, are divorcing after 28 years of marriage.
Robyn Gibson, 53, signed her divorce petition last Thursday and her lawyer filed it with the Los Angeles County Superior Court the next day -- on Good Friday, according to court documents.
A spokesman for Mel Gibson, 53, issued a short statement Monday that he said was on behalf of both husband and wife:
"Throughout our marriage and separation we have always strived to maintain the privacy and integrity of our family and will continue to do so."
The court filing listed the date of separation only as "to be determined."
People.com quoted an unnamed source saying the couple split three years ago, around the time of Gibson's infamous anti-Semitic rant after he was pulled over in Malibu, California, for drunken driving. Watch some of the details on Gibson's divorce situation »
Robyn Gibson's petition asks for joint custody of their son, Thomas, who turns 10 on Tuesday.
The Gibsons have six other children who are all 19 or older.
