Twilight star Kristen Stewart has claimed Hollywood is "disgustingly sexist" and that fame is the "worst thing in the world".
The 25-year-old actress told Harper's Bazaar UK she did not enjoy being famous and claimed it was crazy that women in the film industry had to work harder than men.
The actress plays a personal assistant to a big Hollywood star in the new movie The Clouds Of Sils Maria, opposite Oscar-winning French star Juliette Binoche.
"Women inevitably have to work a little bit harder to be heard," she said. "Hollywood is disgustingly sexist. It's crazy. It's so offensive it's crazy.
"Fame is the worst thing in the world, especially if it's pointless. When people say 'I want to be famous' (I say) 'Why? You don't do anything'."
Ms Stewart told the magazine she put on weight when she ate cheeseburgers but that she was "happy and comfortable".
"If I'm stressed or working, the weight falls off. My weight and my sleep are tied to my nervous system."
"Sometimes I'll sleep for 12 hours a night and sometimes sleep just doesn't exist for me for a couple of months."
In 2012 she issued a public apology to her boyfriend and Twilight co-star Robert Pattinson following claims she had a brief affair.
The Snow White And The Huntsman and On The Road actress had been linked in US reports with the film's British director Rupert Sanders.
