Matthew McConaughey made a surprise appearance at the premiere of his movie “Bernie” on Monday. He wasn’t scheduled to be there but came with fiancée Camila Alves (who hid out inside the AMC Loews 19th Street). “She didn’t have her hair and makeup done, and didn’t want to be photographed,” said a spy. Jack Black walked the carpet, then ran to catch a flight to LA to see his “High Fidelity” co-star John Cusack receive a star on the Hollywood Walk of Fame.
