Kennedy Jr., who was with new beau and castmate from “The Newsroom” Thomas Matthews, was spotted outside the Quintessentially party at Sons of Essex for “Liberal Arts.” “She was asking around for a cigarette,” said a spy. “Someone finally rolled one for her.” Josh Radnor, who wrote, directed and stars in the flick, brought “Twilight” actress Julia Jones, who introduced herself to everyone as “Josh’s girlfriend.”
