Hosted by Johnny Vaughan and Lisa Snowdon, 70,000 fans flocked to Wembley Stadium all keen to catch a glimpse of JLS, Usher, K$sha, Pixie Lott, Alexandra Burke, Chipmunk, Tinie Tempah and Jason Derulo as they all took to the stage.
But there was one act in particular that drove the crowd crazy and that was of course Justin Bieber, who most definitely received the biggest scream of the afternoon.
