Keira Knightley may look like an English rose, but we're happy to report she can swear like a sailor. After working the press line at Monday night's Cinema Society screening of her new film, Atonement, the actress uttered a curse that wouldn't make it into a PG movie. Then again, having flashbulbs thrust in your face will probably do that to a girl. The actress seemed composed enough at the after-party at Balthazar, which drew the likes of Jason Lewis, Eva Amurri, Rosamund Pike, and Josh Groban. "I've been traveling with this film for a while now," she said from her security-guarded corner. "But it's a great cast and a great group to be with. In fact, I'd love to stay longer, but they're making me go now."

Never one to leave a party early, lensman-about-town Patrick McMullan spent Monday evening fêting his new photo tome, Glamour Girls, at the Valentino boutique. Pals like Jay McInerney, Amy Fine Collins, Holly Dunlap, and Tory Burch toasted the photographer, who's as much a mainstay of Manhattan nightlife as cater-waiters and flat Champagne. (Only McMullan's a lot fizzier, of course.) "I got to know Patrick when I was 16 and sneaking out to clubs," recalled Dunlap. "The night I met him, he introduced my friend and me to Mick Jagger and Lou Reed. We actually ended up hanging out with them. They kind of babysat us."

As it turned out, that wasn't the night's only Rolling Stones reference. Back in Soho, Ennio and Carlo Capasa celebrated their company's 21st anniversary and retrospective new book with an in-store cocktail party, followed by a dinner at M Studio. The meal was catered by their aunt Nathalia, Jagger's onetime personal chef. Willem Dafoe, Alan Cumming, and Max Minghella were in attendance, but the real center of attention was Ennio's 14-year-old son, Anton. "My first trip when I was a teenager was to Rome," said the designer. "And here he is in New York! Times certainly have changed." His son seemed to be enjoying his good fortune. When asked what he thought of the city, he had a one-word answer: "Beautiful."
