The 47-year-old actress appears naked in their latest campaign - inspired by the 1960 horror film 'Psycho' - to draw attention to the amount of water wasted in the production of meat.

The images show the blonde beauty cowering in the shower, recreating the iconic moment Anthony Perkins' character Normal Bates stabs Janet Leigh's Marion Crane in the Alfred Hithcock-directed picture.

The advert which features the tagline, "Make a splash for the environment - try vegan", aims to encourage people to banish meat from their diet as the industry is the number one cause of water depletion across the globe.

Long-time vegan Pamela explained: "Rivers are siphoned off, not just for the animals but also for crops grown to feed animals on factory farms.

"Producing one pound of beef uses as much water as about six months of showers."

The spoof images were shot by renowned photographer David LaChapelle.

The former 'Baywatch' could also be set to star in fashion campaigns after she was signed to prestigious modelling agency Next Model Management earlier this year.

Although she is widely thought of as one of the sexiest women of all time, Pamela confessed she thinks the idea of being cast on her looks alone is laughable.

She explained: "I've just signed with Next Modelling agency for commercials and appearances. That is funny. I've never felt pretty enough to be a model. I think I've provoked feelings with how I look. But not as a beauty but as a mischievous little rascal!"
