Friends say Mary-Kate Olsen is “freaked out” about her affair with Heath Ledger leaking to the public. But that hasn’t stopped one-half of the famous Full House twins from shaking her Laffy Taffy all over the Big Apple in the wake of Heath’s death.

Just two days after her Brokeback Mountain booty call was found dead in New York City apartment, Mary-Kate joined her sister Ashley in club-hopping all over Manhattan. She was even spotted making out with New York artist Nate Lowman at dive bar Sweet Paradise.

“She seemed in unusually good spirit,” a Sweet Paradise bartender tells Star Magazine. “It was weird. She sat with a group of friends, having cocktails and laughing, as if nothing had happened.”
