Cityfile: New York's Most Notable and Influential

Happy Birthday | Director Baz Luhrmann turns 47 today. Gossip Girl's Matthew Settle is turning 40. Joe Bastianich, the restaurateur and partner of Mario Batali, is 41. Russian supermodel Eugenia Volodina is 25. Supreme Court Justice David Souter turns 70. American Idol contestant-turned-Broadway star Constantine Maroulis is turning 34. One of the Miller sisters, Princess Marie-Chantal, is 41. Rapper Doug E. Fresh is turning 43. Lakers head coach Phil Jackson is 64. Iowa Senator Chuck Grassley turns 76. And Paula Jones is 43, although she probably shouldn't expect a birthday card from Bill Clinton.

At last night's opening night party for the New York City Ballet's David H. Koch Theater, guest of honor David Koch and wife Julia mingled with Candace Bushnell, Sarah Jessica Parker, Alicia Keys, Al Roker, Debbie Bancroft, Lisa Falcone, Mary Alice Stephenson, Alexandra Lebenthal, Zani Gugelmann, Annie Churchill, Peter Martins, Veronica Webb, Mark Indelicato, Blythe Danner, Valentino, Rachel Roy, Derek Lam, Peter Som, and Vanessa Williams, who all ate, drank, and danced to inaugurate the new Lincoln Center venue.

Say what you want about Lydia Hearst, but she takes her spokesmodel duties seriously. At last night's premiere of Australia at the Zeigfeld Theater, the socialite and erstwhile columnist wore a dress that was, she told the Daily Transom, inspired by the film. But what, exactly, does a floor-length purple halter with Japanese buttons up the side have to do with Baz Luhrmann's epic about an aristocrat and a cattle herder in pre-World War II Australia? "There were actually a lot of Asian seamstresses in Australia during the pre-WWII era," said Lydia. "And you don't see dresses like this anymore." Possibly a good thing, but you be the judge.

Happy Birthday | Restaurateur Joe Bastianich turns 40 today. We're guessing lots of food (and wine) is in store this evening. Also celebrating: Director Baz Luhrmann is 46. Russian supermodel Eugenia Volodina is 24. Rapper Doug E. Fresh is 42. Supreme Court Justice David Souter is 69. LA Lakers head coach Phil Jackson is 63. Former American Idol contestant Constantine Maroulis is turning 33. And one of Bill Clinton's least favorite people in the world, Paula Jones, is 42.
