Mary-Kate Olsen has been snapped with her new boyfriend, Max Snow, who just happens to be Uma Thurman's nephew and heir to an oil fortune reportedly worth $900 million. Teetering along in sky-high ankle boots, an oversized jumper and tights, the mini millionairess was working her distinctive 'dumpster chic' look and seemed very happy to be with her new boy. Mary-Kate was heartbroken when her ex, shipping heir Stavros Niarchos, started dating Paris Hilton, creating a feud amongst LA's hot young crowd, with Lindsay Lohan, Nicole Richie and the Olsens on one side, and the Hilton sisters on the other.
