They were pictured alongside Kendall's model BFF Hailey Baldwin as they partied at the star-studded music festival on Saturday, 11 April.
Kendall turned heads by showing off her super long legs in a black floaty skirt split to the thigh. She also flaunted her tum with a white, off the shoulder crop top.
Fergie, meanwhile, went for an all-black look which included a fedora and fringed over the knee boots.
Kendall is emerging as the It girl of this year's Coachella: as well as hanging with Fergie and Hailey, she's been pictured with Justin Bieber and even Vas J. Morgan from our very own TOWIE!
The reality star's younger sister Kylie is also at the festival, sporting newly-dyed blue hair.
Meanwhile, her older siblings Kim and Khloe Kardashian are currently in Armenia where they've been exploring the country of their late father's ancestors.
