Since it opened back in September, the 18th floor of the Standard Hotel has been the hottest nightspot in New York, with a door policy tougher than Studio 54’s and a design that’s neo-Rainbow Room.

A few weeks later, Madge and her latest boy toy were back for a party they hosted to celebrate the DVD release of Valentino: The Last Emperor.
