Christina Aguilera working on a sensational comeback

Despite starting work on her first film "Burlesque", Christina Aguilera is not leaving her music to one side. The American singer of Ecuadorian origin is stepping up her visits to the studio with producer Tricky Stewart. Stewart was behind Rihanna's massive hit "Umbrella", which can only bode well for Christina Aguilera's next album, which will be her fourth and is as yet untitled.

Tricky Stewart commented: "It's just great. I wouldn't say that it's alternative, I would say that it's different. I really feel it's one of her best bodies of work that I've heard since "Stripped"."
