Scarlett Johansson: 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. It's hard not to feel pressure in this industry and I already use anti-aging products on my skin. 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.
