On Saturday, at the Showcase Cinema de Lux at Patriot Place in Foxborough, Mass., �Justin was in general admission seating for the 2 p.m. showing of Get Him to the Greek,� an eyewitness tells Star. "He was with a bodyguard, his manager, Scott Braun, and another person. Justin snuck out of his seat and tried to get into the premium seating. The problem was that it�s only for people 21 and over. He was caught red-handed and turned away by the theater manager!� The Biebs, who�s only 16, whined to the manager, �Chuck E. Cheese sells alcohol and I have no problem getting in there!� That line unfortunately didn�t work, and Justin, who was in town to open for Taylor Swift�s concert, went back to his old seat. When called for comment, a theater spokesperson said, �We will be happy to invite Mr. Bieber back � when he is of legal age to enjoy our premium seating!�[/align]
