Heath Ledger is back, and apparently haunting ex-Michelle Williams.

Williams is reported to have made the claim on the set of her new movie “Shutter Island.”

“Stunned” co-workers say Michelle claims to have seen Heath’s ghost twice, and that she was “scared half to death” during the first haunting. She claims to have been woken in the night by a series of eerie bumps, and realized furniture in her bedroom was being moved around.

According to the always reliable National Enquirer she caught a glance of a shadowy figure, which she claims was Heath, although she was 100% sure until she saw his ghost the second time.

The second visit apparently included Heath having a chat, and apologizing for not being able to help raise daughter Matilda.

Rate this with a bucket load of salt.
