I had twins - and although was flabby afterwords - was flatter than that. Given that her baby bump was smal during her pregnancy? And it is her first (snap back faster) Really - something just isn't right.

That said - royals and celebs have historically used doubles to duck the media, crowds etc - could be that this is what all this is about. I know I wouldn't want the general public all over the birth of my first child either.
