Hungry revelers in the West Village were surprised when they found Aerosmith frontman Steven Tyler serving slices at Bleecker Street Pizza in the early hours of Sunday morning. Sources tell us Tyler strolled in after midnight with three friends. A witness said, “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.” Tyler is in town for an Aerosmith concert tonight (Nov. 20) at Madison Square Garden.
