Michelle Williams "couldn't stop" touching people after Heath Ledger died.
The 'My Week With Marilyn' actress was left devastated when her former fiance - the father of her five-year-old daughter Matilda - passed away from an accidental drugs overdose in January 2008 and admits one of her ways of coping was doing her best to hold on to the people around her.
She explained: "For a really long time, I couldn't stop touching people's faces. I was like, 'Look at you! You move! You're here!' It all just seemed so fleeting, and I wanted to hold on to it."
The 31-year-old beauty now feels she has "repaired" her life since Heath's death, though she admits the tragedy has completely changed her outlook on the world.
She added in an interview with America's Vogue magazine: "Three years ago, it felt like we didn't have anything, and now my life - our life - has kind of repaired itself ... It's (his death) changed how I see the world and how I interact on a daily basis. It's changed the parent I am. It's changed the friend I am. It's changed the kind of work that I really want to do. It's become the lens through which I see life - that it's all impermanent."
