Will Smith installs paperless loo

Will Smith has installed paperless loos in his home to be more green-friendly.

The actor is saving on toilet paper by using a gadget that sprays water and air on toilet users' backsides.

Smith told The Sun: "It's a gift from heaven, believe me.

"People think it's all about suction and that they're going to have their insides removed by this marvel of modern engineering - but it doesn't suck, it blows.

"Not everyone can handle this thing emotionally, so I've made sure I also have a few normal toilets in my house."
