Kourtney Kardashian Baby, 44 Lb. Weight Loss 6 Months After Second Birth

Kourtney Kardashian is flaunting a newly svelte shape in a teeny weeny yellow bikini thanks to her recent weight loss.

Kardashian, 33, is smiling and confident on the latest cover of Us Weekly. She proudly bares her flat belly thanks to a 44 lb. weight loss.

The "Kourtney and Kim & Take Miami" star posed for the un-retouched photos in Miami on Dec. 13. Inside the magazine, the fashion businesswoman shared the secrets to her success.

"It was harder to lose weight the second time around," Kardashian admitted to Us.

The mother of two admitted that she "gained 45 pounds with Penelope."

The E! reality star has returned to her normal dress size and now weighs 106 pounds on her 5' frame. She gives the credit to a healthy diet and exercise thanks to fitness guru Tracy Anderson. The combination of portion control coupled with Anderson's 90-minute dance workouts has helped her achieve her goals.

Kardashian gave birth to her second child, daughter Penelope on July 8 at Cedars-Sinai Medical Center in Los Angeles. Penelope weighed 7 pounds and 14 ounces. Scott Disick, her boyfriend of six years, is the father of both Penelope and her first child, Mason, 2.

The season finale of her family's reality show, "Keeping up with the Kardashians" was extra special for their fans. Television viewers were able to join the Kardashian brood in witnessing Kourtney give birth to Penelope during that episode that aired in September. 

Kourtney's mother Kris Jenner, her four sisters, and younger brother Rob joined her and Disick in the delivery room.

Viewers were able to watch Kourtney push her newborn out and her family member's reactions to it. Surprisingly, the reality star remained pretty calm throughout the delivery process. Afterward, she described the process as a "magical feeling.

"It's such a magical feeling to say hello to my baby girl," Kourtney said to the camera while her mother cried.

Kourtney stars in "Keeping Up with the Kardashians," "Kourtney and Kim Take New York," and "Kourtney and Khloé Take Miami."

 "Kourtney and Kim take Miami" debuts in January on E!.
