The T4 Stars of 2010 took place in Earls Court on Sunday night and a host of UK artists including JLS, The Wanted, Tinie Tempah, Pixie Lott, Ellie Goulding and Mark Ronson turned up to perform.
The stars led the huge crowd through a selection of hits and accompanying special effects included glitter guns, inflatable globes and lasers.
Most of the artists were followed on Twitter throughout the performances with fans giving direct feedback on the songs and effects.
As he said farewell, host Steve Jones flew through the air on wires, waving at the fans in the higher seats from their eye level.
After the show, JLS led a gaggle of artists like Tinie Tempah and Chipmunk to London's Whisky Mist nightclub to let their hair down.
