One Direction's Harry Styles knocked over by screaming X Factor fans
Simon Cowell's group - including Zain Malik, Liam Payne, Louis Tomlinson and Niall Horan - faced a mob of screaming girls as they arrived at the show's studio in London.
Harry, 16, fell on the pavement as he struggled to get out of a car.
'It was mad, when he got out of the car he was smiling, but then panicked,' fan Miranda Fisher, 16, tells The Sun.
'They all looked like they didn't like it.'
Fortunately, Harry wasn't injured - he was helped up and managed to make his way into the building with his bandmates.
Aiden Grimshaw, 18, also faced a battle to enter the studio.
At one point, he had his back against a wall as he was surrounded by sobbing fans.
