Back in March, Buffington-Quaid filed for divorce, but put the filing on hold a month later, apparently hoping to work things out. However, she filed for a legal separation in October, and Quaid has taken it a step further by filing for a full divorce.
The actor filed the divorce papers with the Los Angeles Superior Court on Friday. Quaid is requesting joint custody of the couple’s 4-year-old twins, Thomas Boone and Zoe Grace.
The star of the current television series “Vegas” has offered to pay spousal support to Buffington-Quaid, according to People magazine.
"Kimberly and Dennis Quaid have decided to legally separate after eight years of marriage," a Quaid representative told Access Hollywood when Buffington-Quaid filed for the legal separation in October. "They ask that their privacy and the privacy of their family be respected during this difficult time. No further statement will be given."
This will be the third divorce for Quaid, who is 58. He was previously married to two actresses: P.J. Soles from 1978 to 1983 and Meg Ryan from 1991 to 2001. Quaid and Ryan have a 20-year-old son, Jack.
