Dennis Quaid's wife has apparently had a change of heart ... 'cause she's officially withdrawn her divorce papers ... TMZ has learned.

We broke the story ... Kimberly Buffington-Quaid filed for divorce back in March citing irreconcilable differences.

It seemed like it was getting contentious because Kim was asking for spousal support but in Dennis' papers ... his lawyer asked the judge to give her squat.

Here's how contentious it seemed -- the judge ordered Dennis and Kimberly to cooperate in deciding who got to use the Range Rover while the divorce was pending.

But in the new documents Kim made it clear she has no desire to pursue the divorce ... and the judge has agreed to dismiss. So marriage back on ... at least for now.

Dennis Quaid and his wife Kimberly Buffington-Quaid are working out a divorce settlement ... according to their rep, but contrary to the rep's statement that everything is going hunky dory, there are clear signs of conflict in the docs.

TMZ broke the story that the couple is getting divorced. As you see from the docs, filed in Austin, Texas, Dennis and Kimberly used initials to mask their identity. Dennis used W.D. -- his name is Dennis William Quaid.  Kimberly Buffington used B.K.

As for the conflicts, Kimberly asked for support in her filing, but Dennis in his response, asks that Kimberly "take nothing."

The Range Rover comment is especially telling -- "The parties shall cooperate with one another in using the Range Rover motor vehicle currently in B.K.'s possession."


Further, Kimberly does say she anticipates she and Dennis will strike a settlement, but she's not fully confident, because she adds, "If such an agreement is not made, Petitioner (Kimberly) requests to divide their estate in a manner that the court deems just and right."

Dennis Quaid's wife has filed for divorce from the actor ... TMZ has learned.

According to the divorce petition filed by Kimberly Buffington-Quaid and obtained by TMZ, "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."

Kimberly is asking for spousal support and attorney's fees.

There is a temporary custody order in place, which provides that both Dennis and Kimberly each get time with their kids. The order only covers last weekend, but presumably they will get an updated order soon. The kids cannot be taken out of state or removed from school without an agreement by both parties or an order by the judge.

The temporary order also gives Kimberly possession of their main residence and the Mercedes.  He gets the Cadillac Escalade and a condo. 

And get this.  The temporary order says, "The parties shall cooperate with one another in using the Range Rover..."

Kimberly is asking that all of their community assets be fairly divided. In Dennis' answer to Kimberly's petition, he says he wants her to get nothing. 

Both Kimberly and Dennis are ordered not to say anything "vulgar, profane, obscene or indecent" to each other.

Dennis married Kimberly Buffington-Quaid in 2004 -- and together, they've been through a lot. In 2007, TMZ broke the story  that their twins almost died shortly after birth because the medical staff at Cedars-Sinai Medical Center in L.A. gave them a massive overdose of the drug Heparin.

The twins are now 4 years old.

It's Dennis' third marriage. He divorced Meg Ryan in 2001 ... and actress P.J. Soles in 1983. 


9:48 AM PST -- Kimberly's rep has released a statement ... saying, "We can confirm that Kimberly Quaid has filed for divorce."

The statement continues, "Contrary to what has been reported, a satisfactory settlement is being worked out for both parties. We will not be providing any further information on this private matter."



Dennis and Kimberly narrowly avoided a legal disaster in 2009 ... when they left a restaurant, seemingly drunk, and Dennis got behind the wheel of his car. Fortunately, a cop advised Dennis to get out of the vehicle before he pulled away ... and the couple got a cab home instead.

A buff and shirtless Dennis Quaid showed off his 57-year-old six pack abs on the beach in Hawaii this weekend.

Quaid can stomach any guy half his age.

Dennis Quaid says he was so coked out of his mind during the time he was shooting "The Big Easy" back in the '80s ... he was sleeping ONE hour a night in between drug sessions.



Quaid spilled his guts about his cocaine addiction in the '70s and '80s to Newsweek ... calling it his "greatest mistake."

Quaid explained, "I’d wake up, snort a line, and swear I wasn’t going to do it again that day. But then 4 o’clock rolled around, and I’d be right back down the same road like a little squirrel on one of those treadmills."

Quaid says he finally realized the severity of his addiction when his band broke up ... saying, "I kind of realized I was going to be dead in five years if I didn’t change my ways. The next day I was in rehab."

In the end, Quaid says the experience helped him grow as a person -- "If I hadn’t gone through that period, I don’t know if I’d still be acting."

Dennis Quaid's looks aren't far from heaven!

Great balls of fire.

Dennis Quaid is shreddin' the gnar ... and his abs.



The 55-year-old hit the surf in Hawaii on Monday and showed off his buff and lean and pale physique.

Quaid just needs some bronzer and a mound of gel and he's ready to join the "Jersey Shore."

GTL!

Cops must have shaken some sense into Dennis Quaid on Wednesday night when they probably let him slide on a DUI -- because the guy splurged on a full-size limo last night just go out to dinner.

Just moments ago, Dennis Quaid returned to the scene of the non-crime -- retrieving the truck that cops suggested he trade for a cab last night outside of an L.A. restaurant called Philippe.


This time, he was able to leave without incident ... we're guessing his bar-top-dancing buddy is still sleeping it off.

Before cops cut Dennis Quaid a break by strongly urging him to get a cab -- instead of a DUI -- his crew was living it up inside Philippe ... on top of the restaurant's bar!


Check out Quaid's friend working her moves on the bar to Aerosmith's "Walk This Way." It looks like Dennis' wife Kimberly was about to join in too.

Anyone got some singles?
