Mary-Kate and Ashley Olsen were both out and about in the Big Apple today. Mary-Kate juggled a phone call, her purse, and an extra-large water bottle as she hopped into a waiting SUV this morning, while Ashley made a stylish exit from a hotel in sunglasses and a summery maxi skirt and flatforms. Ashley was solo as she headed out, and while recent rumors linked her to Justin Timberlake, his rep has made it clear that JT and Ashley are just friends. Ashley split from actor Justin Bartha earlier this year and recently told Style.com that these days, she prefers to keep her social circle small but diverse. As the Olsens point out in that interview, most of their time is devoted to growing their fashion empire, which includes The Row, Elizabeth and James, and their soon-to-launch ecommerce site StyleMint. Their collections have been such a success that Newsweek recently called the duo "America's next billionaires."
