Opera Season has begun in New York City and ET caught up with celebs Christie Brinkley , John Lithgow and Regis Philbin as they arrived to the formal affair! Christie arrived with her son as her date to the opera. She was wearing a gorgeous black Ralph Lauren gown. Lithgow had the night off from working on his Broadway play with Katie Holmes to attend the event. Lithgow talks about working with Holmes and describes her as "marvelous."
