Pamela Anderson has stripped off again for a racy new Valentine's Day-theme PETA ad aimed at urging dog lovers to cuddle up with their pets this winter. The actress/model, who famously starred in a sex tape with her ex-husband Tommy Lee, has a canine co-star in the artistic black and white video, titled La Chienne. In the Deborah Anderson-directed short, Anderson strips off in front of a cute pooch named Monsieur Brando and then climbs into bed with the lucky pup. Accompanying the film is a new message from PETA bosses, which reads: "With much of the country (America) in a deep freeze, Pamela Anderson has gone all burlesque to warm things up in a new PETA video. The message? Keep your dogs indoors and cuddle up with all your loved ones."
