When it was reported just hours after his death that Heath Ledger had died in Mary-Kate Olsen‘s apartment, her rep immediately denied the allegation. However, it turns out that Mary-Kate is involved — she was the first person Diana Wolozin, the masseuse, called after finding Ledger unconscious. Wolozin was let into the actor’s bedroom by his housekeeper after he didn’t respond to phone calls and knocks on his door. She found him lying at the foot of his bed and used the speed dial on Ledger’s cell phone to call Olsen, who was in California, for help, sources told People.com. Olsen told Wolozin she would call her security people in New York to help. The masseuse waited, then called Olsen back to say she was calling 911. Paramedics and Olsen’s security people arrived at almost exactly the same time. Both the New York Post and New York’s Daily News have reported that Ledger and Olsen were dating.
