Two paparazzi sued Pamela Anderson and Denise Richards, claiming the actresses defamed them and Richards assaulted them during a laptop-throwing incident.
Scott Cosman and Rik Fedyck claim in the Los Angeles Superior Court lawsuit filed Friday they've been left with nightmares since the Nov. 9 run-in at the River Rock Casino Resort in Vancouver during filming of Blonde and Blonder
Richards, the lawsuit claims, "stormed up several flights of stairs to their balcony, launched into a 20-minute verbal tirade and physical assault, and called both men 'paparazzi scum.'"
"She pushed and hit both Fedyck and Cosman, snatched their laptop computers from their hands, and threw them over the balcony with total disregard for ... other guests, including an elderly woman in a wheelchair who was struck by one of the falling computers," the lawsuit says.
The complaint also says the women made false accusations to police of harassment, stalking, assault, battery and trespassing and defamed them in public remarks.
Reps for the actresses didn't immediately comment.
Richards has admitted to hurling a computer
that police say slightly injured an 80-year-old woman. At the time, Richards's rep lashed out at the photographers, and no charges were filed. Richards later called her actions a mistake and said she was wrong
Anderson said the Blonde and Blonder
set was plagued bvgby rude paparazzi
and defended Richards. Anderson wrote in her blog: "If it were me I would've thrown the photographers over the edge – they got lucky."
