has taken a swipe at Paris Hilton
- branding her a "silly bitch". 'The O.C.
' star says she's tired of the hotel heiress criticising other successful girls, but insists she isn't trying to compete with the blonde. She stormed: "Paris isn't my rival. I met her one or two times and she's making out there's this big rivalry between us and there so isn't."
She added: "She seems to hate everyone around her age who is more successful. Silly bitch." Mischa - who angered Paris when she started romancing Cisco Adler, the ex of Paris' friend Kimberly Stewart
- also slammed the party girl for pretending she doesn't steal men.
She is quoted by Daily Mirror newspaper as saying: "She does steal other people's boyfriends!" Earlier this month, Paris' sister Nicky
allegedly lashed out at Mischa when she spotted her at a party at the swanky Regent Beverly Wiltshire, in Los Angeles. According to reports, Nicky snapped: "What is that fat pig doing here?", as the sexy actress arrived.
