Michelle Williams -- Devastated

HEATH Ledger's ex-fiancee Michelle Williams is now making a tearful dash from Sweden to New York with their two-year-old daughter Matilda after learning of the Aussie actor's shocking death.Williams, who split with Ledger last September, was in the Nordic country filming her new movie Mammoth.The pair met on the set of Ang Lee's 2005 cowboy epic Brokeback Mountain - for which Ledger scored an Oscar nomination - and he was said to be gutted when the relationship broke down.

Britain's Daily Mail newspaper claimed the 28-year-old began dabbling in drugs."Heath totally wanted to be on his own these past few months since he and Michelle split in September," one insider was quoted as saying."He adored his daughter Matilda and when Michelle called it quits he missed Matilda so much that he was thrown into a deep, dark depression."Heath was living in New York to be close to his daughter. But he hardly ever ventured out any more.

His close friend and Brokeback co-star, Jake Gyllenhaal has been worried about him for months. And he knew Heath was sinking further into a depression. Jake is Matilda's godfather, and he and Heath had become really close since they did the film Brokeback together.Michelle will be devastated by the news because she always hoped ... they could manage to work out their relationship for the sake of their daughter.
