Heather Graham has shared previously unseen photographs of her ex-boyfriend Heath Ledger, who died 13 years ago.
The Austin Powers 2 actor dated Ledger between 2000 and 2001, having met while both were filming in Prague. Graham was working on the Jack the Ripper movie From Hell with Johnny Depp, while Ledger was in the midst of filming A Knight's Tale, the comedy adventure that would become one of his signature roles.

On Instagram, Graham shared three photographs of their time together, along with the caption: "Going through my photos I found these. Just remembering this time. Heath Ledger was such a special person."
One picture sees Graham in costume while filming From Hell, with Ledger having presumably visited the set. Another sees Graham with her arm wrapped around Ledger.
The third appears to be a selfie taken by Ledger while standing in front of a mirror.

Ledger died in January 2008 of a prescription drug overdose in his New York apartment. The Australian actor's death led to an outpouring of grief from across the world.
The Dark Knight, which was the last movie Ledger finished filming prior to his death, was released six months later. His performance as The Joker would win him a posthumous Oscar.
Ledger's other credits included 10 Things I Hate About You, I'm Not There, and Brokeback Mountain, which earned him an Oscar nomination in 2006.
Graham was one of a number of actors Ledger was romantically involved with. Along with dating Naomi Watts and Lisa Zane, he was in a long-term relationship with his Brokeback Mountain co-star Michelle Williams. They had a daughter in 2005, before separating in 2007.
