Isla Fischer is looking svelte after baby

Just three weeks after giving birth to little Olive, Isla Fisher seems to have her petite pre-baby frame back, according to this article and photos on the Daily Mail. You might remember that before giving birth, she was sporting a huge pregnancy belly that apparently was so big that she could no longer drive her car.

Isla's not losing the weight for a movie role -- she's vowed to take her time after giving birth, but she sure is looking great in a hurry. I wonder what her secret is? The article cites breast feeding, which burns at least 500 calories a day. Wow -- that's the same amount of calories that I burn in 45 hard minutes on the elliptical trainer.

I think she looks great -- don't you agree?
