(July 4, 2004 - April 27, 2018) (divorced) (2 children)
Quaid married his third wife, Texas real-estate agent Kimberly Buffington, on July 4, 2004 at his ranch in Paradise Valley, Montana. Together they have fraternal twins, Thomas Boone and Zoe Grace, born via gestational carrier on November 8, 2007 in Santa Monica, California.
On November 18, 2007, hospital staff mistakenly gave Quaid's ten-day-old twins a dosage of heparin 1,000 times the common dosage for infants. Their attorney said the newborns will "be fine now," but Quaid filed a lawsuit against the drug manufacturer, Baxter Healthcare, claiming that packaging for the two doses of heparin are not different enough. In May 2008, the Quaids testified before the United States House Committee on Oversight and Government Reform, asking U.S. Congress not to preempt the right to sue drug manufacturers for negligence under state law.
Buffington filed for divorce from Quaid in March 2012. According to the divorce petition, the marriage had "become insupportable because of discord or conflict of personalities." Buffington's attorney then withdrew the divorce papers on April 26, 2012. In the summer of 2012, Quaid and Buffington moved to California. In October 2012, Quaid and Buffington again decided to separate, and Buffington filed for legal separation, seeking joint legal and sole physical custody of the twins. After waiting to establish the required six months of residency in California, Quaid filed for divorce on November 30, 2012, asking for joint legal and physical custody of the children and offering to pay spousal support to Buffington.
the couple got back together end of March 2013.
It's over — again. Dennis Quaid's wife, Kimberly Quaid, has filed for divorce for the second time, TMZ reports. The mom of two signed court documents in L.A. on Tuesday, June 28, 2016.
