It's been 10 months since Heath Ledger's tragic death. And, obviously, Michelle Williams is still reeling.

In fact, during a recent interview with Newsweek, the actress - mother of Ledger's three-year-old daughter, Matilda - burst into tears at the mere mention of his name. "It's so sad," the 28-year-old told the magazine of Ledger's death - ruled an accidental overdose of prescription drugs - in late January.

How is she holding up? "I guess it's always changing," she said. "What else can I say? I just wake up each day in a slightly different place - grief is like a moving river."

Although the two Brokeback Mountain stars had split before Ledger's death, they always remained close. "It's a strange thing to say, because I'm at heart an optimistic person, but I would say in some ways it just gets worse," she said of her grief. "It's just that the more time that passes, the more you miss someone. In some ways it gets worse. That's what I would say."
