Kanye West and Kim Kardashian at Chateau Marmont on October 20, 2015 in Los Angeles

*Kanye West threw his wife Kim Kardashian a surprise 35th birthday party at the Cinépolis Luxury Cinemas in Westlake, Calif., where he screened new biopic Steve Jobs for an intimate group of family and friends, including Kris Jenner, Corey Gamble, Kylie Jenner, and Caitlyn Jenner.

And the dress code was “Pregnant Kim.”

All the guests were expected to arrive in their “best pregnant Kim look,” according to the birthday girl’s Instagram. Fake baby bumps were provided.

It seems Kim was a little mystified by the theme — “Not sure if that was to make me feel less huge or just a fun cool theme,” she wrote — but guests seemed to embrace it nevertheless:

I wasn’t expecting to look this way again quite yet, but Happy Pregnant Birthday @kimkardashian !! ?????
