Dixon thrilled at 'X Factor' role

Alesha Dixon is "ecstatic" at the prospect of joining 'The X Factor'.

The 32-year-old singer - who is best-known as a judge on the BBC's 'Strictly Come Dancing' - is expected to join Dannii Minogue, Louis Walsh and Take That singer Gary Barlow on the show following the departure of Simon Cowell and Cheryl Cole, who are both working on the US version of the musical talent show.
