Did Heath Ledger Leave Behind a Second Child?

The family of Heath Ledger believes that the late actor may have fathered a secret love child, according to Australia's Daily Telegraph.

Ledger was a 17-year-old when he had an affair with an older woman who is thought to have discovered she was pregnant after the relationship ended.

The woman was living with another man at the time of the alleged affair.

Yesterday, Heath Ledger's uncle, Hadyn Ledger, told the newspaper: "There is a very real possibility that Heath was the father."

If it is confirmed that Ledger is indeed the girl's biological father, it could split his estate between his two-year-old daughter, Matilda Rose, whose mother is Hollywood actress Michelle Williams, and his secret love child.

Heath Ledger, who will star, posthumously, in The Dark Knight, died alone in January in his N.Y. apartment from an accidental overdose of prescription drugs.

The Brokeback Mountain star drew up his will prior to his mysterious death, obviously, and long before the birth of Matilda, on whom Heath doted.

The April 2003 will created by the actor lists only $145,000 in assets and names the late actor's father, Kim Ledger, mother Sally Bell, sister Kate Ledger and half sisters Olivia Ledger and Ashleigh Bell as the only beneficiaries.

The New York documents following his death also acknowledge Matilda Rose, as Heath Ledger's only known child, as an interested party.
