Is Christina Aguilera Pregnant and Who’s the Daddy ?

Christina Aguilera recently announced her divorce from her husband Jordan Bratman.  She revealed that she was starting to find her marriage difficult.  Christina performed last night at the 2010 AMA awards but people were not talking about her performance they were talking about her bump.   Speculation grew that the bump was a baby in the works.    She does look she has packed on a few pounds but give the girl a break it is probably comfort food :-)  What do you think pregnant or not?  If she is pregnant the $64,000 question is – who’s the daddy?
