Alba saves on water by turfing her home

Eco warrior JESSICA ALBA has turfed her Hollywood home with fake grass so her family will never have to use more water than it needs to.

The environmentally-conscious Fantastic Four actress and her husband Cash Warren never have to hose down their lawns.

She explains, "We have a lot of water shortages in Southern California and I grew up with having to take a bath in this much (a little) water and (people saying), 'Don't flush the toilet unless it's, you know...'

"There are all these rules that you just sort of live by when you live with droughts... and when you have turf you don't have to water your lawn at all."
