It's a great day for sex scandal fans: Not only is Eliot Spitzer celebrating his 49th birthday today, but Gina Gershon, now at the center of a controversy over whether or not she had a fling with Bill Clinton, turns 46 today. Other birthdays: Furniture heir Eric Villency is 33. Hedge funder Richard Chilton is 50th. And nightlife impresarios Eugene Remm and Mark Birnbaum will no doubt be partying hard tonight when they turn 30 and 31 years old.
