Cheryl arrived in a bright orange minidress by Hakaan Arussi, which she wore with a pair of stacked Charlotte Olympia courts. The songstress later changed into a multicoloured jumpsuit a la Ziggy Stardust for her on stage performance.
Meanwhile, Katy Perry closed the show in a polka-dot halter and matching leggings for her renditions of “Part of Me” and “The One That Got Away”.
Other super-stars who hit the stage were Chris Martin and his Coldplay band members, Justin Bieber, who showed his love for the UK with a Union Jack vest and a flag on his gloves, rapping super-star Usher, and It-gals Jessie J and Rita Ora.
What a show!
