Mentor: Cheryl Cole

In 2003 Alexandra made it to the very last stages of auditions but didn't make it to the live shows. However her mentor has every confidence in her saying that she has the ability to "sing anything". She has also been coached by Joss Stone in the past.

The north London songstress quite simply stole this year's show. Her powerful duet with Beyonce Knowles singing the track 'Crossroads' was outstanding. Not only is she the 2009 X Factor winner, Simon Cowell believes the soul singer will go on to be as big as Leona Lewis. Her first single 'Hallelujah' looks set to be Christmas No 1.
