Williams arrives for Ledger's funeral

Film actor Heath Ledger’s former girlfriend and 'Brokeback Mountain' co-star Michelle Williams arrived in Australia for the actor’s funeral today with their two-year-old daughter.

Dressed in black, Williams carried her daughter Matilda into the Perth airport terminal after arriving from New York.

Williams, 27, and Ledger became a couple during filming of the gay romance 'Brokeback Mountain', in which they co-starred as husband and wife.

They later moved to New York, and had Matilda, who was born in October 2005.

Earlier today, a handful of young people in casual wear were seen entering or leaving the house of Ledger’s mother, Sally Ledger-Bell.

Ledger’s parents and other close relatives arrived in Perth yesterday after spending nearly two weeks in the US immediately after his death.

Family members attended a memorial ceremony in Los Angeles at the weekend, but have kept funeral arrangements a closely guarded secret.

They are reportedly planning a private service in Perth and will either bury his body or inter his cremated remains in the city.

There was no indication that Ledger’s remains have arrived in Australia. There was no sign of activity at the family’s plot in Karrakatta Cemetery today.

Ledger, who was nominated for an Oscar for his role in Brokeback Mountain, died in his New York City apartment on January 22. He was 28.

Authorities suspect a drug overdose, but toxicology tests are still pending. Police said several prescription drugs were found in the apartment where his body was found.

The New York chief medical examiner’s office is expected to comment this week on the cause of Ledger’s death, after the results of toxicology tests are received.

Brokeback Mountain co-star Jake Gyllenhaal also reportedly plans to attend the funeral.

As Ledger’s hometown prepared for his funeral, residents expressed sadness at his sudden death – and outrage at rumours that he was a drug user.

Much of that speculation was fuelled by video footage showing Ledger at a Hollywood hotel party where drugs were being taken two years ago.
