London, June 10 (IANS) Singer Justin Bieber was embarrassed after he was caught sneaking into the adult section of a cinema hall to watch the new movie 'Get Him To The Greek'.

The 16-year-old singer went to see the film at the Showcase Cinemamovie theatre in Foxborough, Massachusetts, US, with an entourage including his manager and a bodyguard.

He was seated in the general admission area and was given a warning from the hall manager when he reportedly switched seats and headed to the premium section, reserved for adults over the age of 21.

According to dailystar.co.uk, the official was said to have booted the singer out of the adults-only seats and steered him back towards the main auditorium.

A representative for the Showcase Cinema said, 'We will be happy to invite Mr. Bieber back when he is of legal age to enjoy our premium seating.'
