Pamela Anderson Strips Down for PETA, Waves4Water

She's no stranger of using her sex appeal to help causes close to her heart, and Pamela Anderson is continuing along the same path for PETA and Waves4Water.

On Sunday (October 24), the former "Baywatch" babe stepped out at the London Transport Museum in Covent Garden to unveil a new bikini-clad advert for PETA encouraging people to go vegetarian.

Meanwhile, Pam also tweeted about shooting another Playboy spread - with proceeds from her 14th cover going as a donation to the surfer-founded WavesForWater.org foundation.

Miss Anderson wrote, "I’ve just shot another Playboy cover that will debut in January for [Hugh Hefner], at his request. I shot the cover of playboy (only) for a donation to waves4water.”
