Steven Tyler shocked pizzeria customers when he became their waiter. The Aerosmith frontman was in a "great mood" when he arrived at Bleeker Street Pizza in New York's West Village with three friends in the early hours of Sunday morning, and as well as posing for photos with fans, he also took a turn behind the serving counter. An onlooker told the New York Post newspaper: "He was in a great mood and got behind the counter to serve slices to other customers. Steven was friendly and posed for several pictures. He was there for nearly an hour." While the 'Crazy' hitmaker was more than happy to mingle with fans at the pizzeria, his 23-year-old daughter Chelsea - whose mother is Steven's second wife Teresa Barrick - recently revealed he used to go out in disguise to avoid being stopped when out with his family. She said: "I didn't quite understand why we'd go to Disney World and my dad had to wear a fake beard and a big hat, and keep his head down. I was trying to go on rides."
