She's alive! Kate Bosworth showed off her skinny frame spunky attitude at designer Jill Stuart's spring 2007 show at the New York Public Library.

Later that night, the actress -- who's reportedly been nursing a sore throat, which happens sometimes when one doesn't eat -- turned up in black-and-white (right) at a Marc Jacobs after-party. No, she wasn't so pale that there was no color in her skin. We are talking about her clothes, people!

Bosworth, who recently broke up with Orlando Bloom, reportedly gave the designer a silent thumbs up. We have no idea why, but read it in a magazine and are passing it along.
