The 'Boy Does Nothing' singer declared that she is to judge the forthcoming ITV series mere hours after her departure from the Strictly Come Dancing panel.
She revealed on her website that she would be accompanying Simon Cowell, David Walliams and Amanda Holden on the new run of the show.
A statement on Dixon's site said: "Alesha has decided not to return to Strictly Come Dancing after a successful three-series run and will instead be joining the Britain's Got Talent panel, alongside Simon Cowell, Amanda Holden and David Walliams."

A BBC spokesperson said of Dixon's Strictly departure this afternoon: "We wish her all the best. She has done three very successful series with us and we look forward to announcing our new lineup in due course."
Former BGT judges Michael McIntyre and David Hasselhoff announced their exits in September and November respectively.
