Singer Leona Lewis will light up London's Oxford Street this year when she turns on its world-famous Christmas lights next month.

The X Factor winner, who has just rocketed to Number One in the charts with her new single Bleeding Love, will turn on the lights in a special ceremony on November 7.

Thousands are expected to come to see the star at the event on the capital's most famous shopping street, where she is also due to perform her latest track for the crowds.

This year's lights and decorations also mark the release of Disney's family film Enchanted and will see the street transformed into a "dazzling canopy of magic", organisers say.

The film is about a princess who emerges straight from a Disney classic into the modern day reality of New York.

Irish crooners Westlife and the West End cast of Mary Poppins are also set to perform at the ceremony.

The New West End Company, which aims to ensure the area retains its place as a top shopping destination, is behind the event and organises the street decorations.

Jace Tyrell, from the Company, said: "For nine weeks the dazzling canopy of chandeliers will stretch suspended above the heads of shoppers as they zip in and out of the 300 shops lining Oxford Street."
