Mom-to-be Kourtney Kardashian hosted her niece Baby Nori’s first birthday party at her Calabasas, California  home. The celebration for mom Kim Kardashian and dad Kanye West’s first kid had the theme, “Kidchella” party,  prototyped after the popular desert music festival Coachella.

Guests came dressed in festival-type gear and enjoyed a rented Ferris wheel, hippie style Native American peace pipe tee pees, face painting and food carts selling things like churros and lemonade.

“Kim and Kanye made sure it was very special,” a source told PEOPLE magazine.“There were many fun activities for the kids…All the kids had the best time.”

Before this celebration, West and Kim took North out to the Children’s Museum of Manhattan for her actual birthday which fell on Father’s Day, June 15. 

Many of the guests to the home, which previously was owned by pop star Justin Bieber, included aunties, Kylie Jenner, Khloe Kardashian, Kendall Jenner, Jaden Smith, Blac Chyna and her son King Cairo.
