Kylie Minogue and Black Eyed Peas have helped the Jingle Bell Ball to sell out in under an hour.
Tickets to the two-day event, headlined by the Black Eyed Peas on Saturday December 4 and Kylie on Sunday December 5, went on sale at 8am on Monday and before 9am Johnny Vaughan and Lisa Snowdon had to announce live on their 95.8 Capital FM breakfast show that all 32,000 had been snapped up.
Cee Lo Green, The Script, The Wanted, Nicole Scherzinger, Jason Derulo, Olly Murs, Alexandra Burke, Taio Cruz and McFly will also be performing at the Saturday show at the London's O2 Arena.
Akon, JLS, Tinie Tempah, The Saturdays, The Wanted, Flo-Rida, Jay Sean, Example and Labrinth will join Kylie for the Sunday gig.
The Jingle Bell Ball supports Capital FM's flagship charity Help A London Child, who receive a donation from the event's proceeds.
Tickets to the ball can still be won with Capital FM.
