*After giving birth to baby North West prematurely on June 15, Kim Kardashian is already ready to reveal her post-pregnancy body on the afternoon gabfest "Kris."


"Kris" is her mom, Kris Jenner's, show where Kardashian has agreed to go on to flaunt her weight loss since giving birth.


"She wants to show up like Heidi Klum and have everyone marvel at how fast she lost the weight," a source told Us Weekly, adding that Kardashian, 32, has already lost 20 of the 50 pounds she gained during her pregnancy.


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


Kardashian has been staying with her mother Jenner ever since she gave birth. She was told to rest for at lease five weeks, which apparently has Kim "frustrated that she can't exercise yet," the insider said.


Althought quite eager to get her body back, Kardashian's trainer Tracy Anderson said the new mom was in no rush.


"From our talks during her pregnancy, I thought she was going to be really concerned [about her weight] once the baby was out, but she's just not," Anderson said.


"She's in baby heaven. She's excited to get started, but she's really calm about it all."


The celebrity trainer revealed that Kardashian's routine to get her body back would start off with working out four days and week and then gradually turn into five or six.


"Kim is super motivated. She's all in," Anderson said. "Pregnancy is actually an opportunity for women to look better than ever. And [Kim] will."
