An eyewitness tells the new issue of Us Weekly (on stands Friday) that just two days prior, Diaz "was straddling him" at the booze-filled CAA gala at Soho House in West Hollywood. "Her hair was all crazy, her makeup was smeared and they made out in front of everyone," the eyewitness says. "She was acting like a teenager!" (Diaz's rep denies the makeout.)
