Taking to her Instagram stories, Kim documented Chi's birthday. The decor was fit with an indoor maze, hundreds of roses (including placemats made of white roses), and a dessert table with a personalised cake. It didn't stop there though, Kim and Kanye also splashed out on a jumping castle and balloon animal artist.
Celebrity guests included Chrissy Teigen, John Legend and Jen Atkin. Not to mention the entire Kardashian fam, including Khloe, Kourtney and Kendall.
Chicago isn't the only Kar-Jenner celebrating their first birthday though. Kylie Jenner and Travis Scott's daughter Stormi will turn 1 on February 1st, and the family jetted to Turks and Caicos to celebrate.
