Bieber mobbed by screaming fans at airport

POP heartthrob Justin Bieber was mobbed by fans as he flew into London.

The Never Say Never star flew into Terminal 5 of Heathrow Airport and headed straight into a horde of devoted fans who were awaiting his arrival.

The gang of screaming "Beliebers" took photos and tried to grab his autograph as the Canadian star's minders steered him to a waiting car after his flight.

The 18-year-old chart sensation was attending a launch event for his third album Believe which is due out in June.
