At the time of his untimely death in January 2008, actor Heath Ledger was romantically involved -- in secret -- with Lindsay Lohan. So says her mother, Dina, in an undated, recorded phone conversation with Michael Lohan, her ex-husband and Lindsay's father.
In a newly revealed recording at Radar, Dina tells Michael that their eldest daughter "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."
And Ledger's death devastated the actress, now 23. "That f***ed her up," her mother says.
Ledger died at age 28 on January 22, 2008 from an accidental, toxic combination of prescription drugs; he had recently separated from girlfriend, actress Michelle Williams, mother of their daughter Matilda, now 4.
Understandably, the presence of the self-destructive Brokeback Mountain actor made Dina Lohan nervous for her own child's fate.
"When she's drunk or takes an Adderall with it she will do something like Heath Ledger did in a second without thinking," she tells her ex-husband on the tape.
She also expresses concerns about Lindsay's then-relationship with Samantha Ronson, and wonders if her daughter has the wherewithal to walk away. "It's very easy for a rational person to say. But for an irrational person who has a problem with her DNA and alcohol and Adderall and asthma and every other things she's got wrong with her."
For her part, Lindsay Lohan has recently criticized her father for leaking other tapes of private phone conversations. "He's disgusting to do this," she wrote on Twitter. "It really hurts my mom for me and my siblings."
