Kourtney Kardashian is working hard at losing her baby weight, and the effort is paying off big time! Reality's newest hot mama hit her gym in Miami Saturday morning, and RadarOnline.com has the pictures to show the results.
Kourtney, with baby Mason, and her sister Khloe are in Florida where they've been working on a second season of Kourtney & Khloe Take Miami. Kourtney's been working out with her personal trainer at the David Barton Gym every chance she can.
Kourtney and her on-again/off-again boyfriend Scott Disick became first-time parents in December when they welcomed Mason into the world.
