Scarlett Johansson has warned budding starlets to eat healthily when they head for Hollywood, as the pressure to be thin can cause irreparable damage.

The blonde beauty is proud of her voluptuous curves, and has no intention of letting image-obsessed Los Angeles force her to change her natural shape.

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."
