Naomi Watts broke down following an emotional tribute to Heath Ledger at a short film festival in Australia on Sunday.
The 21 Grams star, who was a judge at the annual Tropfest event in Sydney, began crying when a video montage honouring the late actor's career was shown.
Watts dated Ledger for two years after meeting him on the set of Ned Kelly in 2002.

The Brokeback Mountain star was found dead in his New York apartment last month. A New York medical examiner has since confirmed that the 28-year-old was killed by an accidental overdose of prescribed medications.
