Pop star/actress Hilary Duff has hit out at socialite Paris Hilton for her attention-grabbing antics.

Duff, whose ex-boyfriend Joel Madden is dating Hilton's pal Nicole Richie, is less than impressed by the blonde party girl's publicity stunts, which include being photographed panty-less.

She fumes, "Paris brings attention to herself. Some people do things on a night out they know will get talked about."
