Heath Ledger's masseuse called Mary-Kate Olsen 4 times

Diana Wolozin, the masseuse who found Heather Ledger's body in his downton Manhattan apartment on Tuesday night, called Mary-Kate Olsen a total four times – not twice as originally believed, according to the Associated Press.

Wolozin reportedly spent nine minutes making three phone calls to Mary-Kate Olsen before she called 911.

It was not known why the masseuse called Olsen – though the actress was a friend of Ledger's – or why she did not immediately call authorities.

Police sources insist that the calls do not have any significance on their investigation since they believe Ledger was dead when Wolozin arrived.

Wolozin knew that Olsen's number was programmed into Ledger's phone.

A timeline of Tuesday nights events, summarized by Usmagazine.com:

1 p.m. Ledger's housekeeper says she saw him sleeping and heard what she thought was snoring.

2:45 p.m. Wolozin shows up for Ledger's massage appointment and knocks on his door.

3 p.m. She calls his cell phone to wake him up; she sets up her massage table.

3:17 p.m. She calls Olsen. The conversation lasts 49 seconds.

3:20 p.m. She calls Olsen again. The conversation lasts one minute and 39 seconds.

3:24 p.m. She calls Olsen a third time. The conversation lasts 21 seconds.

3:26 p.m. She calls 911.

3:33 p.m. Paramedics arrive and go up in the elevator to the apartment with Olsen's security guards (whom Olsen called to check out the scene).

Paramedics refused to allow the security guards into the bedroom where Ledger is.

3:34 p.m. Wolozin calls Olsen a fourth and final time. The duration of that call is unknown.

3:36 p.m. Ledger, 28, is declared dead.
