The former 'O.C.' star - who is famed for partying with Nicole Richie - insists she prefers to stay out of the limelight and entertain friends at home or walk her dogs.
Mischa Barton told Weekend magazine: "I know I look the part, and people used to come up to me in the street and talk to me as if I was a crazy party girl. But I don't go out clubbing because that whole thing is too claustrophobic. As for shopping, I'd rather walk my dogs, Ziggy Stardust and Charlie Barton.
"I cook a mean lasagne, and some people say my potatoes au gratin are pretty on fire."
The 21-year-old admits her simple lifestyle disappoints many of her fans, but she insists she is nothing like other young female stars who are renowned for their partying.
She said: "I guess some people are disappointed. I'm always being associated with other girls, but we're not in the same crowd. I have only met Paris Hilton once and that was in passing. I am friendly with Nicole Richie, but people see us at parties and assume we all know each other.
"I actually spend my evenings curled up with a good book. Dostoevsky and John Steinbeck are my favorites."
