Poor thing. Must be even worse to do it in the full glare of the media.
I think it's awful that she was forced to announce it so early because of those photographs. There are times and places when the press should keep their nose out, and that's one of them IMHO.
I hate the way that as soon as a celebrity gets the slightest bit plump, there's instant speculation that they're pregnant. The polite thing to do is to wait until they announce it, not demand that they do to sate your desire to sell papers.
But then, I despise the tabloid media altogether.
