Rumours are circulating that singing sensation Christina Aguilera is in discussions to make her West End debut later this year. The Burlesque star was at one point allegedly in the running as a judge on the US X Factor, but instead she now fronts new US hit show The Voice, which searches for the next new American singing sensation with a focus on vocal prowess. Aguilera is one of the show's judges and coaches alongside Maroon 5's Adam Levine, Cee-Lo Green and country artist Blake Shelton.
