Chrissy Teigen's Baby Shower Turn Up Features Kim Kardashian Grabbing Boobs

Chrissy Teigen had a full baby shower turn up ... thanks to Kim Kardashian's camera and her wandering hands.

Kim documented almost every moment inside the ladies only (plus John Legend) bash Saturday -- which featured tons of Mickie D's grub, dancing and a healthy amount of boob flaunting and grabbing.

Khloe, Kourtney, Kris Jenner and Jenna Dewan were also there -- but pay attention to this video, ladies. Guys WILL attend this kind of baby shower!

Lucky man, that John Legend.
