Pamela Anderson's appearance in the hit Borat movie is reportedly a major factor in the demise of her marriage to Kid Rock.

The New York Post quotes a friend of the former Baywatch star revealing Kid Rock's reaction to seeing the film: "He didn't like it... [he] started screaming at Pam, saying she had humiliated herself and telling her 'You're nothing but a whore! How could you do that movie?' in front of everybody."

In the film, Anderson plays herself during a signing event in which Borat, played by Sacha Baron Cohen, attempts to force her hand in marriage. "She was in on the gag from the very beginning and loved doing the movie," added her friend.

The couple officially split last week following a mere three months of marriage, during which Anderson suffered the misfortune of a miscarriage.
