Dennis Quaid has bought a new $3.1 million home for his estranged wife.The 'G.I. Joe: The Rise of Cobra ' actor - who filed for divorce from his wife of eight years Kimberly Buffington-Quaid in November just six weeks after she announced their legal separation - has splashed out on a plush new home for her and their five-year-old twins Thomas and Zoe.The property, which is located in Pacific Palisades area of Los Angeles beside Steven Spielberg, Tom Hanks and Bill Cosby's homes, was purchased last month and the title is held in both Dennis and Kimberly's names but under the terms of their divorce settlement she and their children have exclusive occupancy of the house until they turn 18.The agreement also conditionally allows Kimberly to stay longer if necessary, according to TMZ.com.The actor - who was previously married to actresses Meg Ryan and P.J. Soles - requested joint physical and legal custody of the twins and offered to pay spousal support in his divorce papers.Former real estate agent Kimberly originally filed for divorce last March because she said the marriage had "become insupportable because of discord or conflict of personalities." She later asked for their divorce to be put on hold in April, 2012 to give them time to work on their marriage but then filed for a formal separation in October.A source connected with the couple revealed the reason for the renewed split was that "Kimberly is fed up with Dennis' cheating and wants out of the marriage. He's not a good husband." Dennis, 58, and Kimberley have already overcome a great deal, as their twins almost died shortly after birth because they were accidentally given a massive overdose of a drug at hospital.
