London, January 28 : Kourtney Kardashian, who certainly was under pressure to her baby weight after giving birth to daughter Penelope last July as she is a part of America's most famous reality TV family, revealed the full extent of her incredible 44lbs weight loss as she paraded her trim figure in a series of skimpy bikinis.

With not a hint of flab in sight, the mother-of-two flaunted her enviably flat stomach and toned limbs as she relaxed poolside in Miami.

Emerging from a picturesque infinity pool with the city skyline in the background, the 33-year-old reality star looked every inch the yummy mummy as she showed off her killer tan in fuchsia, cobalt blue and gold halter neck bikinis.

Kourtney showed off her seductive side by reclining on a sofa, while showcasing her envy-inducing curves in all their glory.

The star completed her look with make-up in brown and nude hues to highlight her stunning natural features and her dark brunette locks tumbling in loose waves around her shoulders.

"It was harder to lose weight the second time around. I gained 45 pounds with Penelope. It took me twice as long as last time but I feel healthy and really much better about it," the Daily Mail quoted her saying during an interview with US Weekly magazine.

The star lost the weight thanks to a series of workouts designed by celebrity fitness guru, Tracy Anderson, as well as keeping active throughout her pregnancy.

Kourtney also credits younger sister Kim with encouraging her to hit the gym, even when she's had a long day. (ANI)
