I SWEAR I thought this post was going to be about Jessica Simpson, LOL! I've been spending too much time in the off-season forums...
I agree that she looks both, and they pack on some extra pounds even before the fetuses get very large, but I'm not sure I'd agree with the second part mine around here was pretty damned mean when she was "fat and pregnant!!!" Jason, I busted one the day after Christmas this year that was pregnant with triplets, and was probably easily over 200# on the hoof. And she looked ENORMOUS, but the fetuses were only about the size of a medium-large unshelled peanut or maybe an avg woman's thumb, progress them another month, and I think they'd be likely to be at least twice that size, considering they may be ready to be born as early as 3 1/2 months from now, plus mama needs extra feed to feed them and herself.
I don't know if I would call her fat; maybe "pleasingly plump". Anyway you look at it, that is one chubby deer; pregnant or not.
