Sienna takes swipe at Paris Hilton

Stunning actress Sienna Miller has lashed out at hotel heiress Paris Hilton - saying she hates being labelled an 'It girl' like the American blonde.

Sienna - the girlfriend of Cold Mountain hunk Jude Law - spent years working as a model before kicking off her acting career and is stunned when people assume she's a party girl.

She snipes to America's W magazine: "Do I look like a f***ing Hilton sister? Yeah, and check me out on the internet having sex. The fact is I'd rather be at home cooking."
