"The Island" actress Scarlett Johansson slammed Hollywood celebrities who are constantly on a diet to look skinny, arguing that the pressure to be thin can cause irreparable damage.

Johansson, 21, declared she's proud of her voluptuous body and she has no intention on changing the way she looks.

She says, "Everyone in Hollywood is so damn skinny, and you constantly feel like you're not skinny enough. But I have 'fat days' and I accept that I'm never going to be rail thin.

I try not to let the pressure get to me but Los Angeles is a very hard place to be unless you have people here that love you. It can be very, very lonely and it can eat you up if you don't take care of yourself," Scarlett added.
