Naomi Watts at The Sony 'Tropfest,' the world's largest short film festival - held at The Domain. Sydney, Australia - 17.02.08

Watts, who was a judge at the annual Tropfest event in Sydney, started crying when organisers honoured the late Ledger with a video montage of his career.

King Kong star Watts dated Ledger for two years after meeting him on the set of Ned Kelly in 2002.

The 28-year-old actor was found dead in his New York apartment last month (Jan08). Toxicology results revealed he was killed by an accidental overdose of prescribed medications.
