Rita Cosby’s Book Party at Pacha

Tout le monde was out and about for last night’s party at Pacha for Rita Cosby’s controversial new book ”Blonde Ambition: The Untold Story of Anna Nicole Smith,” hosted by 21 Magazine. For some odd reason, though, roughly one-third of the guests looked — and, worse, sounded — like extras from ”The Sopranos.” Could someone explain what that was about? Also, there were some media luminaries, like Dominick Dunne, Michael Musto, NY1’s Gary Anthony Ramsey, and the ever game Robin Byrd, who appeared to be not entirely un into the whole bridge-and-tunnel gangster vibe from the way she was flirting with the talent.

Update: Radar is reporting that Cosby was served with legal papers on the red carpet of her own event.
