Kylie Jenner seems to be having a peachy-keen time in the desert!

The 18-year-old reality star brought her sister, Kendall Jenner, (and her new pale orange tresses!) to a private 1OAK and Up&Down pop-up party in celebration of day one of the Coachella Valley Music and Arts Festival in Indio, California, on Friday.

Inside the party, which was presented by Bumble, the Jenner girls hung out with Kourtney Kardashian's on-again, off-again boyfriend, Scott Disick. Kylie was all smiles as her big sister's ex wrapped his arms around her while jamming out during an impromptu performance by Post Malone.

Kylie even shared a few Snapchats of the two dancing to the singer's hit, "White Iverson."

Another notable guest? Scott's rumored 20-year-old girlfriend (and Kendall lookalike!), Christine Burke. Though there were no pics of the two together, the model did share a snap of her and her friend, Charlotte Dalessio.

The star-studded party included a surprise DJ set by the Pizza Boys. While hot tracks were spinning, Kendall and Kylie passed out pizzas on the dance floor. Kendall, 20, even assisted with the music by taking control of the Pizza Boys' laptop!

Kylie also got to play DJ for a while, crashing Simi & Haze's set at a party hosted by Paper magazine later in the day.

At one point, Kylie snapped a pic next to an oversized cardboard cut-out of the magazine's April issue -- in which she appears as their cover model -- with her friend, Anastasia Karanikolaou.

Stassie later took to Instagram to share a cute Snapchat video of the two on their way to the party.

"Me and my peach take Coachella," she captioned it.
