She's never been the curvaceous-type, but recently PARIS HILTON's weight seems to have plummeted even more.

The socialite stepped out with current beau BENJI MADDEN yesterday and revealed her shockingly skinny legs.

The heiress-turned-reality TV star-turned-singer's protruding bones were clearly visable, made worse by her skimpy shorts.

The couple arrived in an environmentally conscious Hybrid car and spend the day shopping at DCMA and Fred Segal in West Hollywood, Los Angeles.
