North West's family spared no expense giving her a birthday party fit for a princess [1]. Although North turned 1 in NYC on Father's Day [2], the family decided to celebrate with their friends and loved ones in LA this weekend. Named Kidchella after Coachella, the popular music festival Kendall and Kylie Jenner attended [3] earlier this year, the party was complete with a Ferris wheel, bouncy house, and mini performance stage. With all the attractions, the Saturday afternoon affair gave the social-media-friendly family several photo ops. For starters, sisters Kendall and Kylie took over the stage with pal Jaden Smith, lip-syncing hit after hit as mom Kris Jenner captured it all in videos she posted on Instagram. The sisters seemed at home on the stage one week after hosting the MuchMusic Video Awards, where Kendall turned heads in a sexy and dramatic gown [4]. Kim and Khloé Kardashian also shared snaps, all of which featured the #Kidchella hashtag. Keep reading to see the videos and pictures from North's first birthday extravaganza!
