“Russell Crowe hosted a holiday dinner at a New York apartment on Sunday night catered by Antica Pesa’s Francesco Panella. We hear that the dinner was a preview of the menu that will be available at Feroce — the new eatery Panella’s opening with Tao Group in Chelsea next year. Guests at the gathering of 20 included Crowe’s “The Loudest Voice in the Room” co-stars “Sienna Miller, Seth MacFarlane and a number of other industry friends and actors,” a source said. “There was an impromptu jam session when a guest played guitar and they all sang Christmas carols.”
