Michelle Williams and Heath Ledger
After meeting on the set of Brokeback Mountain in 2005, Williams and Ledger welcomed their first child together, daughter Matilda, in November 2005. Three years later, however, the Dark Knight actor tragically died at the age of 28 of an accidental overdose in NYC in January 2008. "I experienced a lot of loss after his death," the Dawson's Creek alum told The Daily Beast in January 2011. "I lost my city because of all the paparazzi descending upon us." She continued: "It felt as if things were literally slipping through my fingers. Things were just streaming away from me. I lost my sense of humor. I'm still sort of looking for that."
