What is that song???( Xtina fans please help!!)?
In the new Pepsi (i think its for that) Adverts, there is a guy that presses play on his ipod. As the song starts, Christins Aguilera appears and starts sing the song.
Please could some one tell me what that song is called. Im quessing it is from her new CD - Back to Basics, but i could be wrong.
