Mischa Barton, star of The OC, has revealed her contempt for Paris Hilton to London newspaper The Daily Mirror.
Mischa fell out with Paris's posse when she started dating Cisco Adler, the ex-fiance of Paris's friend Kimberly Stewart.
Since then, animosity between the two has been simmering and Mischa is fed up with Paris's gossipmongering.
"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 reportedly told The Daily Mirror reporters at a post-BAFTA party this week.
"She seems to hate everyone around her age who is more successful. Silly bitch."
Mischa, who picked up an Elle Style Award the following night, also ridiculed Paris's appearance at last week's BRIT Awards.
"I tuned into the BRITs because I like to know what's going on in British music and I saw her and I was like 'what?'," the British-born actress reportedly said.
"She was coming out with all this ridiculous stuff like 'I love London because whatever'. Purleese."
Mischa is friends with Paris's ex-bestfriend Nicole Richie, who had a falling out with the heiress while filming reality show The Simple Life.
