While neither of the Olsen twins owned the apartment Heath Ledger was found dead in, the link to Mary-Kate Olsen has finally been revealed.

When the actor hadn’t emerged from his bedroom fifteen minutes later, she called him on his cell phone, but still no response.

She then entered the bedroom and saw Ledger lying in his bed.

Assuming he was asleep, she began to set up a massage table near his bed.

However, when she went over to the bed to wake him, there was no response.

At that point, Wolozin reportedly picked up the actor’s cell phone and dialed Mary-Kate in California (who Ledger had programmed on speed dial) to ask what she should do, knowing Ledger and Olsen were friends.

But now news comes that Heath and Mary-Kate may have been more than just friends.

According to a report in People, the two were dating prior to his death."Mary-Kate and Heath were casually dating for three months before Heath's death," People quotes a source as saying.

"They were hooking up, but neither were particularly interested in making it exclusive."According to police, when Wolozin told Olsen that Ledger was unconscious, Olsen said she’d call some private security people she knew in New York and hung up, the Times reports.

After shaking Ledger again, Wolozin reportedly called Olsen a second time and told her she was calling 911.

According to a new report, police said Wolozin spent nine minutes making three calls to Olsen, with a fourth call being made after the paramedics arrived.

However, according to the Associated Press, police say the calls don’t have a major bearing on their investigation because it's believed Ledger was dead when Wolozin arrived.
