Celebrity Dennis Quaid's Wife Files for Divorce Married since 2004, the couple have two children together By Liz Raftery Published on March 9, 2012 11:10 AM Share Tweet Pin Email Photo: Casey Rodgers/NBC/AP Dennis Quaid’s wife, Kimberly Buffington-Quaid, is ending their marriage. According to court papers obtained by TMZ.com, Buffington-Quaid says she is filing for divorce because things have “become insupportable because of discord or conflict of personalities.” In a statement released to Extra on Friday a rep for the actor said, “We can confirm that Kimberley Quaid has filed for divorce. Contrary to what has been reported, a satisfactory settlement is being worked out for both parties.” The couple, who wed in 2004, have 4-year-old twins, Thomas Boone and Zoe Grace together. Born in 2007, the babies nearly died when they were given an overdose of heparin at a Cedars-Sinai Medical Center in Los Angeles. The Quaids later sued the hospital and drug manufacturer and were awarded $750,000. A temporary custody order indicates that the couple will share custody of the twins. Buffington-Quaid has been granted possession of the family’s main house and a Mercedes, while Quaid, 57, gets a condo and a Cadillac, according to the filing. The couple will share a Range Rover. Last October, Quaid put his 418-acre Montana property on the market for $14 million. This was the third marriage for Quaid, who divorced Meg Ryan in 2001 and actress P.J. Soles in 1983.
