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.
X-Factor and chart star Leona Lewis is launching her own range of cruelty-free cosmetics.
Animal lover Lewis has teamed up with The Body Shop for the products and will also become a "brand activist" for the company.
The vegetarian singer has regularly voiced her views about the treatment of animals and has been a big supporter of an animal sanctuary in Brentwood, Essex.
Her limited edition range of make-up and fragrances is to go on sale from March 26 and she will stage a concert to mark the occasion which is being streamed online.
