Kim Kardashian to Chrissy Tiegen -- I'm Preganter than You!!!

Kim Kardashian and Chrissy Teigen hit the town together Saturday night, and they clearly had stuff in common to talk about.

John Legend was holding on tight as they all left Giorgio Baldi in Santa Monica.  Kanye was there ... just not in the pic.

Chrissy's 4 months pregnant.  Kim's about to pop.
