Happy 2018!

Kim Kardashian and Kanye West rang in the new year at their not-quite-finished Hidden Hills mansion with family and friends last night. While Kourtney was the only sis to appear in this group pic, we suspect Kris was in attendance as well. Of course pregnant Khloe was in Cleveland with baby daddy Tristan Thompson (more on that, coming up).

Nori and Saint were there, as were Larsa Pippen and her kids. A lot of Kanye's creative collaborators were present and the group celebrated outdoors at the couple's new spread -- with thousands of tiny lights illuminating the olive trees and the Provencal-style gardens.

Cutest of all was Kimye's NYE kiss ... watch!
