Five years on: Why we'll always miss Heath Ledger
Heath's love affair with Michelle Williams on the set of Brokeback Mountain was so intense, it was the talk of the film world.
The ethereal blonde liked to joke that he and Jake made out, but she was the one who got pregnant.
He was so taken with fatherhood he took a year off to look after his two girls.
Of the baby, he said: "Matilda is adorable, and beautifully observant and wise. Michelle and I love her so much.
Becoming a father exceeds all my expectations. It's the most remarkable experience I've ever had - it's marvelous."
