Kim Kardashian and Kanye West loaded up the Range Rover and took nephew Mason Disick, niece Penelope, daughter North and makeup artist pal Joyce Bonelli's son Zeplin to Disney on Ice at Los Angeles' Staples Center on Sunday ... as sis Kourtney was at the hospital giving birth to a baby boy!

Kim Instagramed photos of the big day, hashtagged "Disney on Ice #Mason #Zeplin #Penelope #North #BestFriends." (Are all those names really hash tags?!)

A few other pals came along as well, including Ciara and her son Future and BFF forever, Brittny Gastineau and her mom.

The Kardashian Klan sat in the front row with Nori sitting on mom's lap, according to Us Weekly. The report says Kanye was in charge of making sure the kids were fed -- Mason and Penelope were treated to cotton candy. Sounds like a fun (and sugary) birthday for Mason!
