I usually think she looks great and the pic you posted of her yesterday made her look normal. I think this pic was doctored. If not, then she has gone over to the 'body-building' side and looks man-ish.
No, it’s not normal. While yes, you will lose weight from breastfeeding you have to also factor in the fact that she is a SUPERMODEL with supermodel genes. More than likely, as with most supermodels, she has been able to eat normally for most of her life and still have an unbelievably awesome body. Pregnancy is no different. The same rules just don’t apply to her. I mean look at Heidi Klum and her ability to do the VS runway in lingerie a mere 4 weeks after giving birth. They should put a disclaimer on these amazing women so that normal people don’t try to kill themselves to be the same as them.
Still love her though.
