No Joke -- Heath's Ex Spotted with New Man

Someone's got big shoes to fill.

Heath Ledger's baby mama Michelle Williams, along with daughter Matilda, hit a small airport in Santa Monica yesterday along with the new man in her life, director Spike Jonze. Obviously, the photo will only further fuel rumors that the two have reached full-on couple status.

Michelle broke off her engagement to Heath Ledger just a few months before he died of an accidental drug overdose.
