is denying a report she's missing the premiere of The Dark Knight
because of tension with Heath Ledger
"The presumption that Michelle ever intended to attend The Dark Knight
premiere is unfounded, but to say she is 'boycotting' due to a rift with Heath's family is absurd," Williams's rep Mara Buxbaum said in a statement.
She added: "It is time to allow this family to go about their lives without this continued scrutiny and speculation."
Ledger's family confirmed
that they would be flying from Perth, Western Australia to New York City to attend his premiere on July 14, just days before the six-month anniversary of the actor's death. Ledger died on Jan. 22
of a prescription drug overdose at the age of 28.
