FRIENDS of Kid Rock (real name Bob Richie) say his marriage to Pam Anderson ended after four months because he was tired of staying home with the kids while she was out partying.
Yesterday, we told you how the final straw came when Richie exploded after watching his wife in the "Borat" movie - calling her a "whore" and a "slut."
But, "Bob rearranged his life for Pamela," a Rock pal tells us. "He moved from Detroit - something he said he would never do - and moved his son to L.A. to be with her."
But once Rock was in L.A., he found himself a single father to not only his son, Robert James Richie Jr., but to Anderson's two kids, Brandon and Dylan, as well.
"Pamela would go out almost every night and end up at [photographer] David LaChapelle's studio," Rock's friend says. "Bob was home alone with the three kids."
The "Baywatch" babe confirmed that scenario in this month's Blender, which quotes her as saying, "When I go to Hollywood, I start at the Chateau Marmont and then I usually end up naked in David LaChapelle's studio taking crazy pictures. That's usually a night for me. Four or five in the morning, lying across a car in David's studio."
Kid Rock was also said to suspect that Anderson was less than truthful about the miscarriage she claims she had. "Bob never saw any proof or heard from her at any time that she was pregnant. She announced she had a miscarriage. He flew to Canada [where she's shooting "Blonde and Blonder"] to be with her and she went out every night."
As for marital assets, Rock's pal says, "Pamela doesn't have the money in the relationship - he does. She also refused to sign a pre-nup that he asked her to."
A rep for Anderson said, "There was an agreement there would be a post-nup, which was being negotiated up until they split. Pam is a wonderful mother, always there for her kids, and has only been to David's twice since she married. And unfortunately, she absolutely had a miscarriage and only found out she was pregnant a few days before."
An Anderson friend adds, "Every time Pam was shooting her movie, her mother came to watch the kids because Bob was in Detroit recording an album. He never once single-parented her kids."
