Fameball economist, world-class doomsayer, and long-time Gawker favorite Nouriel Roubini had a 14-hour party on Saturday, beginning with a "noon...dip in the model-packed Jacuzzi" atop his Manhattan triplex and ending when the...caffeine ran out, we're guessing. They probably partied until there was no more caffeine left to keep them going at Nouriel Roubini's 14-hour "Carmens and Matadors"-themed party at his $5.5 million apartment.
