Mary-Kate Olsen finds happiness with Nate Lowman

Having hit rock bottom when she was involved with the investigation into the death of her rumored lover Heath Ledger, the diminutive 22-year-old is starting to smile again with the help of her new boyfriend. "They hang out and have fun," says a pal. "He thinks she's cool, and she likes him a lot." The intensely private actress was even happy to indulge in a PDA as she and her man dined at Barbuto restaurant in matching flannelette shirts last week.
