MANHATTAN — Who knew Barbara Bush was such a Lower East Side club girl?
Last night in Manhattan, she was spotted with Leigh Lezark, a DJ with the Manhattan party music trio Misshapes, at Barney's for a book party for fashion writer Derek Blasberg.
His book, "Classy," is an etiquette guide for Manhattan's "Gossip Girl" set.
Meanwhile, Christopher Walken was at Sardi's for the unveiling of his caricature to hang on the famous Times Square restaurant's wall.
The drawing bears a strong resemblance to Walken's "King of New York" character, Frank White. No word on whether he wants us to meet him at the Plaza Hotel about a job.
Walken is currently starring on Broadway in "A Behanding in Spokane" at the Gerald Schoenfeld Theatre.
Lastly, Tina Fey and Steve Carell turned out for an after party at Aureole near Bryant Park for their new film, "Date Night."
In the film, a case of mistaken identity supposedly sends a bored Manhattan married couple on a series of hilarious adventures.
Ben Stiller, Jane Krakowski and New York Jets quarterback heartthrob Mark Sanchez also hit the party.
