Lindsay Lohan's mum has revealed that her famous daughter was dating Heath Ledger when he died.

Dina claimed that the ‘Mean Girls’ star and the ‘Dark Knight’ star were in a relationship at the time of his accidental drug overdose in January 2008.

In a leaked phone call between Dina and her ex-husband, she has said that Lindsay never truly recovered after the Joker actor’s death.

"Lindsay was dating Heath when he died. I don't know if you know that, but I know ''cause I would drop her off and they were friends very, very close, ok?" The Sun quoted Dina as telling Michael in the phone tape.

In the conversation, which was recorded in 2008, Dina attributes many of Lindsay's personal problems to Heath's passing.

She also feared her daughter may end up going the same way due to drink and prescription drug addictions.

"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,” the Sun quoted her as saying on the phone.
