When most stars are airbrushed in photos, it’s to slim them down. But it’s the opposite for super-thin Keira Knightley.

Artists actually have to add curves to her figure. But the 22-year-old Knightley is tired of hearing about her weight. So, is Keira Knightley anorexic or naturally skinny?

At the Venice Film Festival on August 29, she said, “It’s really frustrating,” when reporters kept bringing up her thin figure.

But it was difficult to ignore the fact that the notoriously skinny 5’7″ Knightley seemed to have shrunken even more. “Keira looked shockingly gaunt,” says a witness.

“She is much too thin for her height and at least 20 pounds underweight,” adds Dr. Pescatore, who does not treat Keira. “It is potentially dangerous because most of these stars don’t realize that what they do to their bodies now affects their bodies for the rest of their lives.” [via]
