style.com - Band of Insiders (NY social scene)
The European Union
Core Members: Vladimir Roitfeld, Julia Restoin-Roitfeld, Tatiana Santo Domingo, Margherita Missoni, Stavros Niarchos, Andrea Casiraghi
What do young moneyed Euros do in New York? Stick together. More cliquish than seventh-grade girls, this group's regular haunts include Cipriani, Da Silvano, and anywhere else that can charge $35 for a plate of pasta and keep a straight face. They also congregate at the Washington Square Park town house of longtime couple Tatiana Santo Domingo (the Colombian beer heiress) and Andrea Casiraghi (Princess Caroline of Monaco and Hanover's son). Margherita Missoni, who dates Casiraghi's stepbrother, Ernst of Hanover, is arguably the most outgoing of the bunch (and the most liable to mingle with the other social groups). But Stavros Niarchos, who's reportedly romanced Paris Hilton and Lindsay Lohan, has his own unique way of sampling American culture.
The European Union: The Ladies' Man
For Greek shipping heirs, a playboy lifestyle is pretty much a birthright. Stavros Niarchos, whose namesake grandfather was a rival of Aristotle Onassis, has wasted no time claiming his destiny. As an undergrad at USC he cut a wide swath through L.A.'s female population, puddle-jumping between Hollywood starlets and pretty coeds. Since calling it quits with Paris Hilton over a year ago, he's been playing the field like a pro. Last weekend, he was spotted leaving Socialista with a trio of beautiful women in tow. Corralling his mini-harem into his waiting Escalade, Niarchos did a quick head count. "One, two, three," he said, laughing as he lightly bopped each of his dates on their heads.
