Kardashian, 32, was in Southern California some time in the last few days, keeping a low profile and avoiding paparazzi, reported Radar online.
"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. As for the baby, Kim and her helper kept a blanket over North's car seat so nobody could catch a glimpse," a source said.
"She has dropped quite a bit of the baby weight and it shows. And she really looked like a doting mother, which was nice to see," the source added.
