Pamela Anderson

Celebrity pals Denise Richards (left) and Pamela Anderson have been named in a lawsuit filed by two photographers, who claim the actresses verbally and physically abused them. In a lawsuit, filed Thursday in Los Angeles, photographers Scott Cosman and Rik Fedyck allege Richards raged when she spotted them taking snapshots of her on the set of her upcoming movie "Blond & Blonder" last year. According to the lawsuit, which was obtained by , Richards spent 20 minutes hurling abuse at the two men and physically assaulted them at the River Rock Casino Resort in Vancouver, Canada. The plaintiffs claim Richards then "snatched their laptop computers from their hands, and threw them over the (hotel) balcony," adding one of the computers allegedly struck "an elderly woman in a wheelchair." Canadian police investigated the incident and decided it "wasn't in the best public interest to bring criminal charges" against the actress. In the lawsuit, Cosman and Fedyck claim Richards and Anderson, her "Blond & Blonder" co-star, then falsely told the Royal Canadian Mounted Police that the photographers "had engaged in criminal activity." As a result, they were arrested and held by authorities for "approximately three days." Cosman and Fedyck are suing both women for assault, battery, defamation, false arrest and other charges.
