Allison Williams: 'Weight critics make my job tough'

Girls star Allison Williams has taken aim at the critics who constantly comment about her weight and look, revealing the scrutiny is the most "stressful" part of her job.

The actress, 26, became a viral sensation in 2010 after posting a video of herself singing a mash-up of Nat King Cole's Nature Boy and RJD2's A Beautiful Mine - the theme song for TV drama Mad Men.

Producer Judd Apatow was so impressed after seeing the video he cast her in Girls, opposite the show's creator Lena Dunham, but what should have been a joyful time in Williams' life turned sour quickly when fans and critics alike started writing and posting negative remarks about her apparent weightloss.

Naturally tall and thin, Williams, who will portray Peter Pan in a live TV event next month (Dec14), has opened up about dealing with the fall-out from fame in a new Allure interview.

She explains, "When I did the Mad Men thing, I was graduating from college - you're college-weight. And so when we filmed the pilot for Girls and even into that first season, I looked like someone I hadn't looked like for four years.

"But that's still the way it was set in people's minds, so they're like, 'Oh, my God, you've lost weight'. And I'm like, 'This is just the way my body is very naturally'.

"It's a little bit stressful to know that there are a lot of people walking around who think I'm constantly just shaking and depriving myself."
