Skinny starlet Mary-Kate olsen is said to be mulling over a mega-bucks contract to become the new face of Calvin Klein. The younger of the olsen twins (by just minutes) has been treated for eating disorders and is said to be back down to a frightening 40kg. Her twin sister, Ashley, is said to be against any fashion deal because it would hurt their own clothing line. Meanwhile, Mary-Kate is gloomy over reports that her billionaire boyfriend, Stavros Niarchos III, is romancing a number of gold-digging cuties throwing themselves at him in St. Tropez. She and Stavros recently had what appeared to be a blissfully happy Hawaiian vacation together.
