Paris Hilton, Nicole Richie and Nicole Kidman are the latest stars who seem to be shrinking before our very eyes.

Paris wore leggings that highlighted her bony limbs during a Coffee Bean stop in West Hollywood yesterday.

And Paris wasn't the only Hollywood starlet showing off their dwindling frame on a coffee run.

Nicole Richie and boyfriend Joel Madden took time out from being first-time parents to baby Harlow to get their caffeine fix from Baja Fresh.

New mum Nicole's skimpy vest top revealed that she seems to be rapidly losing those much-needed post-pregnancy curves.

As does Nicole Kidman who showed off her bony cleavage during promotional duties for new film Australia.
