Next Friday, 13th November, the girls will be heading over to Cheshire Oaks designer outlet in Chester, to take to the stage and also switch on the lights of Britain's biggest Christmas tree!
The huuuge tree stands at a massive 90 feet tall, carries 80,000 baubles and it'll be up to the girls to switch on its 100,000 lights!
Before the big switch-on, you'll be able to see some fantastic music onstage, with the girls headlining and Mr. Hudson and dance phenomenon Basshunter on hand to support.
