London was lit up by a bevy of big name celebrities tonight as Regent Street's famous display was launched with a bang.
A spectacular display of fireworks lit up the sky as Leona Lewis turned on the lights, along with Emmy Award Winning actor Ty Burrell and Hollywood film director Rob Minkoff.
As well as flicking the switch, the former X Factor winner performed to a jam-packed Regent Street crowd.
She was followed by other big names, including Emma Bunton and Melanie C, Eliza Doolittle, Passenger, Imagination, MKS, Gabrielle, Richard & Adam, Only The Young and Jahmene Douglas.
This year's lights depict the brand new DreamWorks animated film Mr. Peabody and Sherman release in February.
