By Daily Mail Reporter PUBLISHED: 09:18 EST, 1 February 2014 | UPDATED: 13:02 EST, 1 February 2014 Despite the latest allegations that New Jersey Governor Chris Christie knew about plans to block entrances to the George Washington Bridge last year, the governor was out hobnobbing with celebrities like Jon Bon Jovi and Jimmy Fallon last night. Christie attended a birthday party for shock-jock Howard Stern on Friday - the same day his childhood friend, and former adviser announced that he has evidence that proves Christie was lying when he claimed to have no prior knowledge of the lane closures until after it happened.
