Girlband The Saturdays will light up London when they turn on the Christmas lights in Oxford Street.
The girl group will flick the switch on the mile-long lights next Tuesday.
They will also perform their new single, My Heart Takes Over, at the event at the Marks & Spencer store at Marble Arch.
Jace Tyrrell of the New West End Company said: "London's iconic Oxford Street lights will capture the imagination of the tens of millions of visitors over the Christmas period to the West End.
"That includes international shoppers coming from as far as China, Russia, Japan, Brazil and Thailand for a quintessentially British Christmas.
Other acts that have turned on the lights include Westlife, Leona Lewis, the Sugababes and the Spice Girls.
