Kim Kardashian Post Baby Weight: Lost 20 Pounds Since Birth Of North West, Will Debut Post Pregnancy Body On Kris Jenner Talk Show Like Heidi Klum?

Kim Kardashian received a lot of criticism during her pregnancy with baby North West. Now reports say Kim has lost 20 pounds since giving birth to her baby, and will debut her post-pregnancy body on Kris Jenner's new talk show.

The Daily Mail reports that 32-year-old Kim will reveal her post-pregnancy bod on her mother's talk show, "Kris." This will mirror Heidi Klum's surprise appearance on the Victoria's Secret catwalk in 2009, just three weeks after giving birth.

"She wants to show up like Heidi Klum," a source told Us Weekly. "...and have everyone marvel at how fast she lost the weight."

"She won't leave the house until she's thinner," the source added.

According to Us Weekly, Kim has already lost 20 of the 50 pounds she gained while pregnant.

Some sources claim they spotted Kim out in public with her newborn daughter last week.

"Kim looks amazing, she really does. She's dropped a lot of the baby weight already ... not to say she still doesn't have a ways to go, but she looked slim and was glowing," an onlooker said.

"As for the baby, Kim and her helper kept a blanket over North's car seat so nobody could catch a glimpse."

The new mom is resting with baby daddy Kanye West at her mother's home. Kim was told to take it easy by doctors for at least five weeks, which apparently has Kim "frustrated that she can't exercise yet," the insider said, The New York Daily News reports.

Kim's trainer, Tracy Anderson, said that pregnancy is actually a great opportunity "for women to look better than ever."

"And [Kim] will," Anderson promised.
