Anderson, 39, and Rock, 35, both filed divorce petitions Monday, each citing irreconcilable differences, but they gave different dates of separation. Anderson's papers said they separated before Thanksgiving weekend, on Tuesday, Nov. 21, 2006, while Rock – who filed under his real name, Robert Ritchie – said they separated on Sunday, Nov. 26. No reasons were given for the discrepancy.

Both ask that the court not get involved in awarding spousal support.

The couple held their first wedding ceremony on July 29 on a yacht in St. Tropez. In a note posted on her Web site the following day, Anderson described the nuptials as "The best most romantic wedding of all time."

They later made it legal on Aug. 3 at a Beverly Hills courthouse, and held a third, surprise wedding on Aug. 17 onstage at Nashville's Tootsie's Orchid Lounge.

Earlier this month, Anderson's rep confirmed that the actress had suffered a miscarriage while in Vancouver filming the movie Blonde and Blonder.

The marriage was Anderson's second; she was married to Mötley Crüe drummer Tommy Lee from 1995 to 1998 and has two sons with him – Brandon, 10, and Dylan, 8. Rock has a 13-year-old son, Bob Jr., with former flame Kelley South Russell.

Anderson and Rock had dated and broken up before: They first got together in spring 2001, became engaged in April 2002 and then split in June 2003.

They rekindled their romance this July when they ran into each other in St. Tropez on a yacht owned by a mutual friend. "It was like we'd never been apart," Rock told PEOPLE on July 11. Although they weren't expecting to see each other, "it turned out great. She had the kids there and it was so nice to see them and it was wonderful. Love her to death."

Anderson revealed on July 18 that she and Rock were planning to wed, writing on her Web site: "I've raised my kids alone in hope of a miracle. Well my miracle came and went. And came back and came back because he knew that I'd wake up one day and realize that I was waiting for nothing. I'm moving on ... I feel like I'm finally free ... I'm in love. I'm happy."

Hate to see this happen. Call me twisted, but I always liked them together.

Eh. I couldn't care less...although I'm still a little sad for Pamela and her miscarriage. Kid Rock though - eh.

But yet gays aren't allowed to get married?! Jeeze.

Who cares about Pam and her never ednig marriages? Tommy Lee called this one.

all can think of is that song, another one bites the dust

Now they're saying on the 'Net that Kid Rock got jealous over Pam being in Borat and called her a whore.

It keeps getting stupider and stupider...

I read they broke up because he likes meat. And she is strictly PETA.

Pamela Anderson's passion for animals might be one of the reasons she filed for divorce from Kid Rock. In an ironic case of bad timing, December's GQ Magazine crowned Pamela Anderson and Kid Rock their "Newlyweds of the Year." Sorry TomKat.

In the article, the trashtastic two were asked if Pam's work with animal rights had gotten Rock to abandon his love for hunting. Kid replied, "Now I shoot the deer and she saves it." A shocked Pam responded, "What did you say? That's divorce right there. You shoot anything, it's over."

They say meat is murder, and perhaps in Pam's case, also grounds for divorce.

Now it's his turn: Kid Rock's friends say that he had to end his marriage to Pam Anderson because he was sick and tired of taking care of their kids -- while Pam would stay out 'til all hours.

Yesterday, it emerged that Pam couldn't deal with her rocker hubby's anger and insecurity issues, including a public blow-up at a private screening of "Borat," as Page Six reported. Today, friends of Kid (real name: Bob Ritchie) tell the Post that once he moved to L.A. from Detroit to be with Pam, Bob found himself constantly at home with his son (and Pam's two boys with Tommy Lee), while Pam was out carousing almost every night.

Ritchie's friends also say that he suspected that there wasn't really a miscarriage, as Pam claims, because he had never heard from her or anyone else that she was pregnant. Whatever the case, say the rocker's pals, "Pamela doesn't have the money in the relationship – he does." Pam's reps say she is "a wonderful mother" and "absolutely had a miscarriage."
