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

After delivering her baby premature on June 15, Kardashian has been staying with Jenner, 57, as she rests. The new mom 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.

Recently, Kardashian's trainer Tracy Anderson said the new mom was eager to get her body back, but 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 days.

"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."
