Justin Bieber is bringing Bieber Fever to London to turn on the Christmas lights at both Westfield shopping centres.
The 17-year-old pop star will appear on stage in The Atrium at Westfield, Shepherd's Bush on Monday November 7 to count fans down to the switching on of the lights, before performing four of his hit singles, including new song Mistletoe.
Bieber Fever is expected to see 10,000 people descend on the shopping centre and 100 lucky fans will be taken backstage to meet Bieber.
The Baby singer will then be whisked across town to Westfield Stratford City to turn on the lights from the outdoor Chestnut Plaza, followed by a special fireworks display over the Olympic Park.
Bieber will again perform four songs and meet a select group of lucky fans.
The teenage heartthrob will be joined on stage at both centres by children from Westfield's Christmas charity the Teenage Cancer Trust.
Last year Rihanna turned on the Christmas lights at Westfield.
