Keira Knightly is topless on the cover of the December issue of Allure. No big deal though.

"I don’t mind exposing my (breasts) because they’re so small," she says. "People really aren’t that interested!”

We beg to differ. But maybe that's because we've never seen her boobs in person and, according to her, they're often digitally enhanced.

"They always pencil in my boobs,” she says. “I was only angry when they were really droopy. For King Arthur, for a poster, they gave me these really strange droopy tits … I thought, well if you’re going to make me fantasy breasts, at least make perky breasts.”

Knightly's latest film, Anna Karenina, hits theaters Friday (Nov. 16).
