Keira Knightley refuses to keep a TV in her house because she's convinced she would become an addict if she had access to reality shows.
The Pirates of the Caribbean star prefers to read or sketch, and is even considering cutting off her internet connection to ensure she makes the most of her free time.
She tells Britain's Elle magazine, "Do you know what it is? It's that I'm the laziest f**ker in the entire world. It's true. And stagnation is always really, really imminent.
"I can literally just sit and not do anything for hours and hours and hours and if there is something completely mind-numbing to do, like surfing the internet or watching cr**py TV, I'll do it and then I'll feel s**t about myself. So I try and get rid of it."
Knightley now counts TV as a guilty pleasure, and admits she is fascinated by U.K. ballroom dance competition Strictly Come Dancing.
She adds, "A lot of my friends don't have TVs either. It might be spreading. But what's nice is that when I do see it, it's such a treat. I did a photoshoot in Cornwall recently and a friend of mine was on the shoot and we literally just sat in my room watching Strictly Come Dancing. We were like, 'This is amazing.' We were talking about that for weeks afterwards."
