Michelle Williams won't move out of the house she shared with Heath Ledger.

The 'Blue Valentine' actress - who has a five-year-old daughter Matilda with the late actor - insists she doesn't get upset by living in the New York property she shared with her ex-fiance, but she isn't sure she could live there alone.

In an interview with website The Daily Beast, she said: "This is a lived-in house. There are seven people living here at the moment. I couldn't live here alone. You could live here if you want. We have a very open-door policy."

Heath died at the age of 28 from an accidental prescription drugs overdose in January 2008 and Michelle, 30, admits 'The Dark Knight' star's passing triggered a series of unexpected losses in different areas of her life.

She explained: "I experienced a lot of loss after his death. I lost my city because of all the paparazzi descending upon us. I actually lost my journal during that time, oddly enough. I literally couldn't hold on to anything. It felt as if things were literally slipping through my fingers. Things were just streaming away from me. I lost my sense of humour. I'm still sort of looking for that."
