London: Singer Justin Bieber`s recording was interrupted when 300 young girls invaded ITV`s studios here in an effort to meet him.

The 18-year-old was at the location to record ‘Alan Carr`s Summer Spectacular’ and there were only three security guards to control the crowd.

"It was genuinely scary. They`re only teenage girls but they were hysterical and had just one thought on their minds to see Justin Bieber. It was pandemonium," a source told

The bosses managed to shut the doors to the main building just in time.
