Christina Aguilera on Connan and The 2010 American Music Awards

In spite of gaining a little weight-  by Hollywood standards-and looking a little tired, Christina Aguilera is still out there promoting the release of her upcoming film Burlesque.

Firstly at the 2010 American Music Awards where she performed Express and more recently on Late Night With Conan O’Brien where she sang the jazzy, Something got a hold on me.Both Performances were a little sloppy and lacklustre, with her voice sounding darker and heavier than usual.However, there's no denying she still has amazing pipes.

Am I being too harsh? Let me, and the world, know what you thought of the performances.
