What is up with these celeb moms trying to make us mere mortals feel like failures? It seems as though every new celeb mom breaks her predecessor's record for losing the baby weight.

Isla Fisher seems to be back to her pre-pregnancy size a mere THREE WEEKS after giving birth to a baby girl (the Dad's Sascha Baron Cohen, a/k/a "Borat.") As photos and a report from NOW Celeb News Network indicate, the actress has gone from not being able to fit inside her Mini Cooper, to strutting down the red carpet, all svelte and sexy again. In 21 days???

What's even more mind-boggling is the fact that Isla claims not to have changed her diet. How did the pounds melt away? Breastfeeding!!!

New moms, take heed!
