Leona will turn on Oxford Street lights

Leona Lewis has agreed to turn on the Oxford Street Christmas lights next month.

The singer, who hit the number one spot this week, will be the special guest at the event on November 7.

Lewis is expected to perform her hit 'Bleeding Love' before switching on the festive lights along the famous shopping street.

The X Factor winner will be joined by Westlife and the cast of the musical Mary Poppins at the switch-on.

The Christmas lights will be based around the Disney movie Enchanted, which is released at UK cinemas on December 14.
