Gwen Stefani will switch on Westfield London's Christmas Lights on November 30.
The 'Hollaback Girl' hitmaker - who features in the shopping complex's festive advertising campaign - will make a rare trip to the UK to sing songs from her new holiday album 'You Make It Feel Like Christmas' in front of just 7,000 people, with 100 lucky fans getting the chance to meet their idol on the night.
Of her festive gig, Gwen said: "I'm excited to be a part of Westfield's Christmas campaign this year. The holidays are one of my favourite times of the year and Westfield's holiday 'Lights Switch On Event' is the perfect backdrop to perform for my London fans and share my new Holiday album, 'You Make It Feel Like Christmas'."
Myf Ryan, Westfield UK & Europe's Chief Marketing Officer said: "We are delighted to have the iconic Gwen Stefani perform live at Westfield London switching on the Christmas lights to help sprinkle some holiday magic across the centre. Westfield creates unforgettable festive moments to bring family and friends together and share truly unique experiences, and Gwen's performance will be a really special moment for our customers."
Following the release of the No Doubt singer's album, the 48-year-old star is getting her own NBC show named after the record, which will air on December 12 at 9pm.
It's said to be a "modern take on traditional Christmas specials", and will feature an hour filled with sketches and performances.
Gwen - who has sons Kingston, 11, Zuma, nine, and three-year-old Apollo with ex-husband Gavin Rossdale - will be joined on stage by her country musician boyfriend Blake Shelton for a duet of 'You Make It Feel Like Christmas'.
