Former X Factor contestant and winner Alexandra Burke has been confirmed to perform at CLIC Sargent’s annual Christmas Celebration.

The event, which will be held at the Royal Albert Hall, is on December 10 and is hosted by the UK’s leading children’s cancer charity. The ‘Bad Boy’ singer is no stranger to the event as she took part in it back in ‘05.

Burke recently finished the Inca trek in Peru to raise both money and awareness for Breast Cancer Care after revealing that she had found a lump that luckily turned out to be a benign cyst.

Tickets are available now for the concert, which will also feature a 1,500 strong choir of school children along with performances by All Angels, Dionne Bromfield and dance crew Urban Strides.
