Slideshow: Quickest Celeb Marriages Ever

Baywatch beauty Pamela Anderson has filed for divorce from singer Kid Rock after just a few months.

"Pamela filed for divorce last week," Anderson's rep, Tracy Nguyen, reportedly told People Magazine. "It wasn't a happy Thanksgiving."

On Monday, Anderson posted the following message on her Web site: "Divorce Yes, it's true. Unfortunately impossible. "

According to People, Anderson, 39, and Rock, 35, both filed divorce petitions Monday. They both reportedly cited irreconcilable differences.

The magazine reported each person gave different dates of separation. Anderson's papers reportedly said the couple separated on Nov. 21. Rock, whose real name is Robert Ritchie, said they separated on Nov. 26.

Both Ritchie and Anderson asked the court not to get involved in a spousal support settlement.

People magazine reported that the pair had three wedding ceremonies, with the first being on a yacht in St. Tropez on July 29. After that, they legalized their union on Aug. 3 in a courthouse in Beverly Hills and then held a surprise wedding on Aug. 17 onstage at Nashville's Tootsie's Orchid Lounge.

There were reports earlier in November that Anderson recently had a miscarriage.

Anderson was previously married to rocker Tommy Lee, of the band Motley Crue.

They were wed from 1995 to 1998. From that marriage, she has two sons.

Ritchie has one son with a former girlfriend.
