Gwyneth Paltrow made a stylish appearance at Williams-Sonoma in NYC yesterday. She wore a blue button-down shirt and a Band of Outsiders pencil skirt to sign copies of her cookbook, It's All Good, at the Upper East Side store location. The Big Apple stop was the latest in Gwyneth's press tour for her health food tome, following events in LA last week. Gwyneth headed East Monday, and enjoyed a celebrity run-in while catching her flight out of LAX. She documented her meeting with Demi Lovato on Twitter, writing "Apple, look who was on the plane!" Gwyneth will likely be headed to the terminal again soon, as she is scheduled to be in Munich, Germany, to promote Iron-Man 3 with Robert Downey Jr. next week.
