Rocker Steven Tyler stunned onlookers at a New York diner over the weekend (17-18Nov12) by stepping behind the counter and serving pizza to customers.

The Aerosmith star visited Bleecker Street Pizza with three friends in the early hours of Sunday morning (18Nov12) and he offered his assistance to workers at the eaterie.

A source tells New York Post gossip column Page Six, "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."
