The Wanted Surprised By Backstage Magic Money Trick At Jingle Bell Ball - Video
The 'Glad You Came' boy band were led through a magic trick backstage at the O2 Arena by magician Katherine Mills.
The Wanted were surprised backstage at the Capital Jingle Bell Ball 2012 by a magician, who brought a drawing of a goldfish to life in a glass of water.
Max George, Nathan Sykes, Tom Parker, Jay McGuiness and Siva Kaneswaran were also surprised to see a ten pound note magically increase in value.
'All Time Low' singer Max George was asked to draw a goldfish, which came to life before the band's eyes and started swimming around in a glass.
The Wanted wowed the crowds at this year's Jingle Bell Ball, performing their biggest hits on stage, including 'I Found You' and 'Chasing The Sun' to the 16,000-strong audience at London's O2.
