Heart breakfast presenters Jamie Theakston and Emma Bunton are hosting the Regent Street Christmas Lights Switch-On event this year.
And Emma Bunton will become one of the acts as she is being reunited with her former Spice Girls band member Melanie C to sing a song or two.
Also appearing at the event on Saturday 9th November will be Leona Lewis, Passenger and Eliza Doolittle, followed by Actor Ty Burrell and Hollywood film director Rob Minkoff who will both flick the switch.
Emma Bunton said: “It’s my favourite time of the year and what better way to kick it off than by singing our 1996 Christmas number 1 ‘2 become 1′ with Melanie C at the switching on of the Regent Street Christmas lights! It’ll bring back a lot of nostalgia for us and all our fans. See you there!!”
Emma announced the news on Heart breakfast on Friday.
Melanie C said: “I’m so excited to be performing at the Regent Street Christmas Lights this year with my lovely friend Emma Bunton. We both absolutely love this time of year and have so many wonderful Christmas memories – this will be one to cherish”.
