I dunno....
Jessica Simpson looks a tad preggers to me. She is not a "fat" girl by any means, oh, I know she has had her weight fluctuations, but all in all she has always looked good and in proportion. I know a simple pair of Spanx could tuck that tiny tummy in, unless of course it's even bigger than we are seeing. She certainly doesn't look heavier to me, in fact her face and arms look slim. I am going to say that either Jessica should have chose a different dress or she just doesn't care that she's pregnant and it shows.
