A week after giving birth, FitCeleb Minnie Driver is mini again. The new 38-year-old mom - who welcomed son Henry Story Driver on September 5- debuted her post-baby bod during a trip to the grocery store Saturday in Malibu, Calif. Son Henry went along for the ride in his black stroller. Her slim size is quite a feat, considering Henry weighed in at 9 lbs., 12 oz. While pregnant, Driver told Usmagazine.com she pigged out on olives.

"I dream about enormous olives," she said in March. "It's great just to be able to eat! No guilt! No guilt about anything."Still, she admitted to, "I'm not as hungry as everyone told me I'd be."

I don't know how these new moms look as though they never gave birth! Have any of you lost your baby weight in record time?
