DIVA Mariah Carey will switch on the dazzling Christmas lights to mark the opening of Wonderland at Westfield on Thursday (Nov 19).

The pop princess will also hold a special signing session to launch her new album, Memoirs of an Imperfect Angel, and her new perfume, Forever.

In an exclusive appearance, the shopping centre will provide glitz and glamour as the Southern Terrace is transformed with VIP pink carpet, fans and snowfall confetti for a parade from 6pm to 6.15pm.

This will be followed by turning on the lights at 6.30pm and singing in the atrium between 6.30pm and 8pm. Jill McArdle, head of marketing for Westfield London, said: "We're very excited to have Mariah at Westfield London.

"Her music is timeless and has great appeal to customers of all ages so she's the perfect star for us.

"She's also a big fan of the Christmas season."
