Mischa Barton slams "silly" Paris

Mischa Barton has slammed "silly bitch" Paris Hilton for implying that the two have an equal rivalry.

The star of The O.C. laughed off reports that the pair were at each other's throats after Mischa started dating Cisco Adler who was engaged to the heiress's pal Kimberly Stewart, saying that the heiress was a silly bitch.

She told The Mirror: "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 seems to hate everyone around her age who is more successful. Silly bitch."

The actress also mocked Paris's appearance at the 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?'

"She was coming out with all this ridiculous stuff like 'I love London because whatever'. Purleese."
