Not quite keeping up with Kim! Kendall Jenner flashes her perfectly pert derrière in skimpy yellow thong ʙικιɴι

Her older half-sister Kim has broken the internet several times over thanks to her famous behind.

However, it seems Kendall Jenner isn’t quite as cheeky as the Kardashian side of the family as she continued her stint at the Cannes Film Festival by hopping on board a luxury yacht on Tuesday.

The supermodel, 21, slipped her famous figure into a skimpy yellow ʙικιɴι and cropped crotchet poncho which still managed to flash her peachy derriere – before switching to a skimpy pink ʙικιɴι as she carried on frolicking on the boat’s deck.

On top of the world: Kendall Jenner, 21, slipped her famous figure into a skimpy yellow ʙικιɴι and cropped crotchet poncho which still managed to flash her peachy derriere as she continued her stint at the Cannes Film Festival by hopping on board a luxury yacht

Kendall, who was joined by her oldest sibling, Kourtney, 38, who looked sensational in a black ʙικιɴι, kept her brunette tresses straight while a large straw hat casually fell off her head and was held in place with its tie detailing.

Despite looking like the ultimate beach babe, Kendall proved to have enough with that swimwear look as she changed into a saucy pink ʙικιɴι – and ditched her cover-up.

The plunging frilly ʙικιɴι top tamed her ᴀssets in place and she added a dainty gold chain to her flawless decolletage.

A pair of matching high-waisted ʙικιɴι bottoms, which boasted large ʙuттons down each side, exhibited her toned stomach as she reclined on a wooden ledge.

The reality star looked on fine form as she placed one glistening leg over the other one as she soaked in her sun-drenched environment.

The beauty, who opted for a simple coat of make-up, tied her locks into a ponytail for her second look and ensured her oversized hat was positioned properly on her head.

However it wasn’t long before Kendall wanted a piece of the action and made her way down the stairs to enjoy a spot of tubing with her pals.

The star, who is dating rapper A$AP Rocky, looked like she was having a blast as she swished across the ocean while laying on her stomach on the inflatable.

Hoping back on board, Kendall once again showed off her fine form as she made her way to an outdoor shower to freshen up.

Meanwhile mother of three Kourtney, who has been gallivanting around town with her new toyboy lover Younes Bendjima, 23.

The sisters enjoyed a night on the tiles on Monday as they headed to the Gotha nightclub.
