The Australian actor unexpectedly passed away aged 28, leaving behind his former partner, Michelle Williams, and their daughter, Matilda Rose Ledger.
Overnight, Heath's former girlfriend, Naomi Watts, posted a moving tribute on Instagram, writing: “Thinking about this beautiful soul today.”
“10 years ago he left this world. He was a true original. Heart always on his sleeve, with the most powerful charisma, strength, humor and talent. I will never forget his gentle spirit.”
Heath and Naomi were in a relationship from 2002 to 2003, and remained close friends until the actor's death in 2008.
“We had a beautiful relationship, only a couple of years, but he was a man who was completely full of joy, and there was a lot of laughing and affection,” she previously told More magazine.
“He was really a very special soul and made a great impact on my life. And a great actor, but I know there was so much more to come. And it’s a tragedy for his little daughter.”
