Actress Kristen Stewart says that Hollywood is "disgustingly sexist" and fame is "the worst thing in the world".

"Women inevitably have to work a little bit harder to be heard. Hollywood is disgustingly sexist. It's crazy. It's so offensive, it's crazy," femalefirst.co.uk quoted the 25-year-old star as saying.

Stewart also doesn't understand why anyone would want to be famous.

"Fame is the worst thing in the world. Especially if it's pointless..." Stewart told Harper's Bazaar.

While she enjoys acting, the `Twilight` actress admitted that she occasionally gets stressed out and it can impact her weight.

"I'm a little bigger than sample size when I'm eating cheese burgers and am 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," she said.
