Pamela Anderson drank a glass of filthy water on US television to show how a cheap new filter can make water safe for drinking.
Anderson was promoting charity organisation Waves For Water on the Ellen DeGeneres Show when she agreed to demonstrate to the host how new technology turns filthy liquid into drinking water in the world's poorest regions.
"This is a crude, simple thing; it's based on dialysis - if you can clean blood, you can clean water... It's drinkable; I'm gonna drink it right now," dailystar.co.uk quoted her as saying.
"I took them (the filter bags) to India when I went to India and did a demonstration there and I gave it to a bunch of people and then they take it to different places and we just keep on kinda spreading it around... the slums of Brazil, my friends are there right now," she added.
