Who knew being a mommy was such a good workout!
Kourtney Kardashian was spotted taking her little princess Penelope to her baby class in Beverly Hills, and it certainly looked like she had her hands full!
The fashionable mommy did some heavy lifting as she carried her little genius in one arm and a Prada diaper bag in the other!
Ok, so we're guessing little Penelope doesn't weigh much at all. But seriously, when did Prada get into the diaper bag making business??
Ch-ch-check out more pics of the two beauties out and about (below)!
