MARY-Kate Olsen obviously moves on quickly - just days after being the first person called upon the discovery of her "friend" Heath Ledger's body, the actress has been spotted steaming up the dance floor and hooking up with a mystery fella.

Olsen, now back in New York after spending the week in Los Angeles, reportedly gyrated sexily at a hip downtown club before kissing a male friend in her entourage.

The New York Daily News today revealed the night of frantic partying came just hours before Olsen made a brief public statement about Ledger.

Released by her publicist, the statement was the first word from Olsen since the Australian-born actor's death. In its entirety it reads:

"Heath was a friend. His death is a tragic loss. My thoughts are with his family."

It's also been a tough week for masseuse Diane Wolozin. First she found Ledger’s body - then she had to handle the controversy surrounding her three phone calls to Olsen before she rang for an ambulance.

Now she could face charges. The New York Education Department notified the NYPD yesterday that she does not have a license to practice in New York.

Under state law, anyone not authorized to practice a licensed profession could be charged with a felony.
