Was Beyonce sporting a fake baby bump?

For about as long as Beyonce and Jay-Z have been married, there's been speculation about what's going on in Beyonce's womb. Now that she confirmed at the MTV Video Music Awards that she is with child, the deniers are speaking out.
Over at Mediatakeout.com, they're saying Beyonce was wearing a "prosthetic belly." To be clear, they aren't saying she is NOT pregnant, just not pregnant enough to have any sort of noticeable bump.
"She wanted the announcement to be dramatic, so she made sure she had a baby bump," the website quotes a source as saying.
I say: This is really, really ridiculous
