Celebrity Mel Gibson's Wife Files for Divorce The estranged couple seek to "maintain the privacy and integrity" of their family By People Staff Published on April 13, 2009 12:20PM EDT Photo: Steve Granitz Archive/WireImage Mel Gibson’s wife of nearly 30 years, Robyn Moore, has filed for divorce, PEOPLE has confirmed. The couple released the following statement Monday: “Throughout our marriage and separation we have always strived to maintain the privacy and integrity of our family and will continue to do so.” Moore, 53, citing irreconcilable differences, is seeking joint physical and legal custody over their minor child, Thomas, 9, according to court papers. She is also seeking spousal support and attorney’s fees, and is asking the court to deny her husband any spousal support. Gibson, 53, met Moore, at the time a dental nurse, in the late 1970s after the American-born actor, who moved to Australia when he was 12, had filmed his breakthrough success, Mad Max. The pair, both now 53, married on June 7, 1980, and have seven children – Hannah, 28, twins Edward and Christian, 26, William, 24, Louis, 21, Milo, 19, and Thomas.
