As a new day dawns here in the UK, the news of Heath Ledger's death is no less shocking. As people wait to here the out come of Heath's autopsy, thoughts turn to his family and his ex-lover Michelle Williams. The Dawson's Cree' star has reportedly been left 'devastated' by news of her former fiancee's death. Williams, who has a two-year-old daughter Matilda with Ledger, was on location in Sweden when news of his death broke. She is now reportedly making her way back to the U.S with her daughter, People magazine reports. "She's devastated," a source close to 27-year-old Williams said. The couple were together for three years, after meeting on the set of Brokeback Mountain, in which she played the wife of Ledger's gay cowboy character. The couple were often rumoured to be on the verge of tying the knot, but eventually split last September. "I can't believe Matilda is going to grow up without a dad, without knowing her father," another source told People. "And that Michelle will have to deal with having a daughter who's lost her father. She's a survivor. She'll make it, but it's going to be hard. Her first concern is going to be Matilda." Pictures: Fernado Allende / Isabella / Prahl / Splash News
