Heath Ledger and Mary-Kate Olsen were dating

Heath Ledger and Mary-Kate Olsen were dating, it has been claimed.

As previously reported, a masseuse who arrived at Ledger's SoHo apartment on Tuesday first called Olsen before 911 when she discovered the Australian born actor's body.

The New York post claims that Ledger, 28, had Olsen's number programmed into his phone.

According to America's New York Daily News newspaper, Olsen's bodyguard later confirmed to police that two were dating (though her rep insists they're just good friends). The NYP quotes a police source as saying the two had a "mutual relationship."

According to a law enforcement official who spoke to the Post, the masseuse called Olsen, 21, first because "she didn't want a media circus." The Daily News reports that the masseuse called Olsen "for guidance."

Olsen told the masseuse she would send her security guards to the apartment.

After the masseuse tried to rouse Ledger, she discovered that his body was cold, the Post reports, so she called Olsen again. "I think he's dead," she said.

Olsen coldly replied: "I already have people coming over."

The masseuse then told Olsen she was calling 911.
