Ledger's ex arrives in Perth for funeral

Heath Ledger's ex-fiancée Michelle Williams has arrived in Australia to attend the actor's funeral.

The 27-year-old and daughter Matilda, 2, flew into Perth earlier today and were escorted off the plane by security guards and police.

Ledger's dad Kim, mother Sally and sister Kate returned to the city from LA yesterday.

Details of the ceremony have not been released, but it is thought the Brokeback Mountain star will be buried alongside two of his grandparents in a family plot.

He was found dead at his Manhattan apartment on January 22 at the age of 28. The cause of death is expected to be revealed after toxicology tests are completed later this week.
