Pamela Anderson has taken another stab at stripping off for Peta - by recreating the famous Psycho shower scene.

The 47-year-old actress is transformed into a Hitchcock blonde for the new black-and-white poster, which sees her posing naked in the shower with just a tiny wet towel to cover her modesty.

The Baywatch star is the face of the latest Peta (People for the Ethical Treatment of Animals) campaign against water waste in the meat trade.

The caption reads: "Meat and dairy farms drain a third of the world's water. Make a splash for the environment - try vegan."

The picture was taken by celebrity photographer David LaChapelle.

Anderson has stripped off for Peta campaigns on several previous occasions, including posing naked in the window of Stella McCartney's London shop in 2011 in a protest against animal cruelty in fashion.
