Bringing her a-game to the festival, which is known just as much for its fashion as its music, Kendall wowed in an over the shoulder white crop top and high-waisted maxi skirt on day two of the event.

The teen’s skirt featured two deep slits on the front, with the model flashing her toned and tanned legs as she strolled round the site.

The little sister of Kim Kardashian accessorized her bohemian getup with metallic body chains across her upper body for added bling.

As night fell Kendall added a Chicago Bulls baseball cap to her boho look, which looked like it belonged to Justin, as her group checked out the day two acts which included Jack White, Tyler the Creator and FKA twigs.

Justin meanwhile played it cool in a hoodie, as he let his hair do the talking, pulling his blonde locks up into a ponytail.

The music star promptly took to his Instagram page to show off his new look alongside a male pal.

The Beauty and a Beat hitmaker was spotted sharing a close conversation with Kendall as they listened to the headline acts, although the nature of their relationship is currently unknown.

The captionless intimate picture showed Justin holding onto the Keeping Up With The Kardashians star’s hips while soaking up the sun at a private residence.

The two appeared rather close, with the Baby hitmaker leaning over the model’s shoulder.

His lips were inches away from her neck as he stood shirtless, clad in a pair of orange New York Knicks basketball shorts.

Bieber has been friends with the Kardashian-Jenner family for years, with the singer a close pal of Kendall’s older sister Kim.

He was also spotted hanging out with Kendall’s 17-year-old sister Kylie on the first night of Coachella on Friday, when the pair hit a party at Beacher’s Madhouse.

Keeping close to one another, Justin and Kylie attempted to go incognito as they headed inside the party located in Indio.
