Lindsay Lohan was dating Heath Ledger when he died, her mother has claimed. Dina Lohan alleges the “Mean Girls” actress was romantically involved with the “Dark Knight” star when he died of an accidental drug overdose in January 2008 and has never fully recovered from his death.

Dina told Lindsay father Michael in a leaked phone call published on Radar Online: “And she was dating Heath when he died? I don’t know if you know that, but I know because I would drop her off and they were friends very, very close, ok?”

Dina – who is divorced from Michael – fears Lindsay’s reaction to Heath’s tragic death is the cause of her many personal problems and may eventually prompt her to accidentally take her own life.

She said in the 2008 phone call: “When she’s drunk or takes an Adderall with it she will do something like Heath Ledger did in a second without thinking.”

“His death f***ed her up.”
