Kate Bosworth Rejoins The Super-Skinny Brigade

It looks like Kate Bosworth has pushed her dieting too far.

The actress is known for her yo-yo weight but has been looking healthier recently after becoming dangerously thin a few years back.

But yesterday, the already slim actress she stepped out looking painfully skinny again.

The Superman Returns star was all bones as she posed on the red carpet at the 2nd Annual Elysium Heaven Gala in Los Angeles on Sunday.

Kate's boobs and bum were non-existent and her collar bone jutted out from her figure-hugging dress.

Stop shrinking Kate!
