Claire Danes and Orlando Bloom hook up on the dancefloor.

Looks like Kate Bosworth is about to be blue crushed. The actress’s longtime boyfriend, actor Orlando Bloom was recently spotted snuggling up to another lady. The girl in question, Claire Danes has a boyfriend of her own, Billy Crudup. Are two high-profile Hollywood break-ups on the way?

According to Page Six, Bloom spent Saturday night getting close to Danes at the Raisa Gorbachev Foundation party in Northamptonshire, England. They began dancing as the Black Eyed Peas performed and things got hot and heavy. An onlooker said, "He was kissing her neck and grinding against her. He didn't seem to care who saw it."

This wouldn’t be the first time Danes has been the other woman. Crudup famously left his pregnant girlfriend, Mary Louise Parker, for Danes while they filmed Stage Beauty in 2003.
