Mary-Kate Olsen let her hair hang loose leaving a friend's place in NYC yesterday. She's holding down the fort on the East Coast while Ashley and her boyfriend Justin Bartha had a bit of a scare this week when their plane had to make an emergency landing as they were flying to LA. He wasn't too shaken up to hit the red carpet the next night, however, as he joined a handful of other actors honoring his National Treasure producer Jerry Bruckheimer. Mary-Kate and Ashley are busy with their separate personal lives and they just made another joint business transaction. They finally sold the West Village penthouse they bought when they first arrived in the Big Apple to attend NYU, making over $1 million in profit despite never actually living in the apartment.
