The single ladies at the Cinema Society party for “The Social Network” Wednesday night were more interested in Cameron and Tyler Winklevoss than the boldfaces at the Gansevoort Park Avenue hotel. At the end of the brilliant movie, the audience learns the brothers settled a lawsuit against Facebook’s Mark Zuckerberg for $65 million. The square-jawed, identical-twin Harvard grads, were more popular at the after-party than the film’s stars Jesse Eisenberg and Justin Timberlake, or hunks Marcus Schenkenberg and Billy Crudup. And the Winklevosses might become even wealthier — they’re suing Facebook again, claiming they were lied to about the company’s value when they settled the earlier suit. Facebook is now worth $25 billion. Also there: Helena Christensen, Bridget Moynahan, Gabourey Sidibe, Baz Luhrmann and Brett Ratner.
