Michelle Williams MWILLIAMS072606_01.jpg We expected poor Michelle Williams to be rocked by the loss of Heath Ledger - but it sounds like the actress may need even more time to recover than we thought!

People is reporting that plans for filming Blue Valentine, Williams' next movie, have been suspended while she copes with Heath's death.

"We will hold off until she is ready," a source connected with the film told the mag. "The production is in the process of sorting it out in respect to her."

Production, originally set to start on February 25th, has been pushed back indefinitely.

"We're hoping she will still come back and do the film and are happy to wait," the source says. "The film is tailor made for [Williams and co-star Ryan Gosling] so of course we would want to wait. You can't get much better than them."

Poor Michelle - we'd hate to hurry along her grieving process, but we sincerely hope she's able to come back from this tragedy sooner rather than later!
