If Mary-Kate Olsen is trying to prove that she and her Weeds co-star, Hunter Parrish, aren't a couple, she's doing a pretty good job of it. The pint-sized star was seen having a very hot 'n' heavy make-out session with a tall, "scruffy" guy at a dinner in Paris, Page Six reports. Spies say the guy pushed MK against the wall and kissed her passionately while the crowd went wild. And to finish off their very public display of affection, MK wrapped her legs around the guy, which scored them a standing ovation from the other guests at their table. Sounds like she had a pretty yummy dessert that night!
