Actor Heath Ledger's former partner Michelle Williams has spoken publicly for the first time since the star's death, saying: "My heart is broken."
Michelle Williams played Heath Ledger's wife in Brokeback Mountain
In a short statement, she said: "Please respect our need to grieve privately."
Williams, an actress, met Ledger on the set of their film Brokeback Mountain and the couple had a daughter, Matilda, who is now two.
But the pair split up last September. Australian star Ledger died in New York in January at the age of 28.
Results of the toxicology tests, which will determine the cause of his death, are expected in the coming days.
His body has been flown home to Australia for a private burial. A public memorial service has been planned in Los Angeles.
The statement from Williams comes after a video of Ledger at a Hollywood party, in which he said he used to smoke cannabis, was pulled from US TV "out of respect" for the late actor's family.
