DENNIS QUAID's third marriage is a bust! His wife, KIMBERLY BUFFINGTON-QUAID, has filed for divorce.

"The marriage has become insupportable because of discord or conflict of personalities … that destroys the legitimate ends of the marriage relationship and prevents any reasonable expectation of reconciliation," the divorce petition explains.

Kimberly is asking for spousal support and attorney's fees. She wants all of their community assets be fairly divided. In Dennis' answer to Kimberly's petition, he stated he wants her to get nothing.

As far as their 4-year-old twins — who almost died shortly after birth in 2007 due to a massive overdose of the drug Heparin — there is a temporary custody order in place so that both Kimberly and Dennis have access to the kids.

To prevent a public feud, the couple are ordered not to say anything "vulgar, profane, obscene or indecent" to each other.

Quaid was previously married to MEG RYAN and actress P.J. SOLES.
