Kim Kardashian finally showed her face in public after birthing baby North West -- surfacing at an L.A. medical facility Wednesday -- and giving us a glimpse at her post pregnancy bod ... sorta.These are the FIRST photos of Kim and Kanye West with their daughter since KK popped back in June, and everyone looks happy and healthy. Hell, even Yeezy was smiling as they walked into the doc's office ... with a nanny-assist, naturally. No shot of North's face though ... she was fully covered in a car seat. Mama K was all top secret too -- concealing her figure under a baggy button-down with another shirt tied around her waist and famous cheeks ... for extra coverage. Hey, Kim knows her body is a cash cow -- and she ain't giving away the milk for free.
