Demi Moore picked up a stray kitten, which managed to crash an exclusive Chanel party on Wednesday night at Miami’s Art Basel, and took it to dinner as her date. According to sources, the 50-year-old actress picked up the cat when it wandered by the Soho Beach House’s pool. “The kitten sat on Demi’s lap throughout the meal . . . She was cuddling and petting it,” the New York Post quoted a source as saying. After dinner, the Ghost star ditched the feline and went to a packed after-party for art-collecting site Art.sy. Wearing a very short pantsuit and black-rimmed glasses, she squeezed onto a sofa with Lenny Kravitz swilling can after can of Red Bull.
