The actor, 53, and Kimberly, 35, are the biological parents, Quaid's publicist, Lisa Kasteler, told the Associated Press Monday.
The couple married on the Fourth of July in 2004. Quaid's best man was his now 15-year-old son, Jack Henry Quaid, whose mother is the actor's ex-wife, Meg Ryan.
The former Kimberly Buffington was a Texas real-estate agent when a mutual friend introduced her to Quaid in March 2003 at a dinner in Austin.
Quaid, who is currently shooting The Express, was married to actress P.J. Soles from 1978 to 1983 and to Ryan from 1991 to 2001.
