The birthday party, which happened post a week the tot turned one, was titled 'Kidchella' after the annual Coachella Valley Music and Arts Festival.
Kim Kardashian's mother Kris Jenner posted pictures from the party on Instagram. "#TheGoodLife #kidchella #norths1stbirthday," she wrote.
Kris Jenner posted a video in which daughters Kendall and Kylie are seen singing along to Rihanna's 'We Found Love' as Jaden Smith, Kylie's rumored boyfriend, and other male friends dance on the mini stage.
North's birthday was officially on June 15, but with the big day falling on Father's Day, the family kept the celebration in New York laid-back.
"Ray of clouds. Chirping of birds. Gurgling of water. Granting desire. One with water. #Kidchella my first Coachella!!!" Kim's sister Kourtney Kardashian wrote with a photo.
The party took place in the backyard of Kourtney and Scott Disick's new home in Calabasas.
