Kourtney Kardashian, who welcomed her second child last July, reportedly dropped a whopping 44 pounds after giving birth to daughter Penelope — and now Celebuzz has the photos of the end result.

Seen in a parade of colorful bikinis, the Kourtney & Kim Take Miami star flaunts her flat stomach and toned limbs in a series of freshly-released photos.

”It took me twice as long as last time but I feel healthy and really much better about it,” wrote about the body transformation in her Celebuzz blog early this January.

“It’s all about priorities and living life!”

According to Kardashian, 33, her success is attributed to a combination of exercise, healthy eating habits and active mommy duty — such as pushing around a stroller — in between playtime with Penelope and three-year-old son Mason.

“It wasn’t even an option to think about going crazy and overdoing it with exercise [this time around],” the mom-of-two said in an interview with Us Weekly.

To drop the baby weight, the mom-of-two enlisted the help of celeb trainer Tracy Anderson, who in the past has worked with A-listers such as Gwyneth Paltrow and Madonna.

Kardashian also attributes her weight lost to her sister Kim‘s unwavering support.

“If she wasn’t scheduling the workouts, I probably wouldn’t have been as motivated,” she admitted.
