“There’s an obsessive quality to it that I thought I would’ve grown out of by now,” said Anne, who lost 25 pounds for Les Miserables. “It’s an ongoing source of shame for me.”
The Devil Wears Prada beauty added that the white hot glare of the spotlight, and always having to keep up appearances, contributes to her stress.
“I just think about the ridicule you get if you have an off day,” Anne told the magazine. “If people weren’t watching, I’d be so much more eccentric. I know it makes me sound weak, but rather than make myself happy and wear the silly hat and say, ‘Oh, I don’t care.’
“I actually really don’t feel like getting made fun of,” she said. “So I put on something boring and navy and go out and try to disappear.”
