Mini Kim K. Stages Birth of Mini Kanye's Baby

0617_kimye_beachers_mad_house_wmKim Kardashian's mini-me gave birth this weekend -- LIVE on stage -- complete with Mini Kanye and even a mini-baby ... yes, that's possible. 

Just hours after the real Kim gave birth ... Mini Kim pretended to pinch out a baby of her own during Beacher's Madhouse at the Roosevelt Hotel in Hollywood Saturday night.

The lil cast included a little person playing lil K&K's baby girl -- and the real Kim K's real BFF, Jonathan Cheban, just happened to be in attendance to deliver the kid.
