Jessie J, James And Conor Turn On Xmas Lights
Stars turn out in London's Oxford Street for the big festive switch-on...
The pop stars were joined by Capital FM presenters Lisa Snowdon and Dave Berry for the festive switch-on, which saw Jessie perform a selection of her hits - including Price Tag - before they all pressed the button together.
Costing a reported £1.5m - the festive illuminations are made up of three quarters of a million LED bulbs.
J-Arth has been crossing swords with former The X Factor winner Matt Cardle again in the wake of his first week album sales falling short of those achieved by Cardle.
