Christina Aguilera looking so fat now when She's apears on the stage for "Michael Jackson tribute concert" last night. we all dont knowing what Christina do with her body.

We think the "What a Girl Wants" singer need to more hard working to get back her shape body. more workout at the gym's maybe will help Cristina Aguilera body into fit again.
just compare Cristina pictures on 2009 with her pictures last night, its make all of her fans so sad.
