Cameron's shame: Cameron Diaz is doing everything she can to stop a Russian Web site,
www.scandal-inc.com, from selling a video of her made in 1992 when she was an aspiring model, age 19, in which she appears high-heeled and topless and, along with another young model, poses "torturing" a man. "A cease and desist letter has been sent to the Web site" to prevent it from distributing the S&M video, which it began offering for download yesterday for $39.95. What, exactly, is Diaz shown doing? "Walking" a leather-masked man like a dog -- and spraying her breasts with compressed air and exclaiming, "Whoa! Look at them! Look at how big they got!" Poor dear. (Page Six and Rush and Molloy)
