Keira's thin in genes

Keira Knightley has slammed rumours she has an eating disorder - saying being thin is in her genes.

The stunning actress says she owes her toned body to her father and gets hurt when critics say she's too thin and is starving herself because her grandmother used to suffer from anorexia.

She said in an interview with Britain's Reveal magazine: "My dad's tall and thin, so this is my body. I can pretty well eat anything I want and I don't work out as I find it very boring. However, saying that, my grandmother had anorexia in the 1940s - a time when it wasn't fashionable to be thin."

Meanwhile, Keira says her face is so covered in spots she has to cover them up with her fringe.

The 'Pirates of the Caribbean' beauty said: "Spots have always been a problem. The fringe is fantastic. It completely covers everything."
