Kendall Jenner struggles to contain her perky assets in TINY string bikini as she peruses a drinks menu while frolicking poolside in Miami

She is known to sashay down runways all around the world. 

Yet Kendall Jenner was taking her supermodel prowess from the catwalk to the pool on Wednesday as she put in a showstopping display in Miami. 

The Keeping Up With The Kardashians star, 24, looked incredible in a scanty bikini with a tiny top and bottoms which flashed her posterior and a mass of underboob as she was joined by her sister Kourtney Kardashian, 40, and pal Bella Hadid, 23, the Daily Mail reports. 

Kendall looked phenomenal for the outing as she made the most of her lithe physique by opting for as little material as possible. 

She scraped her hair into a high ponytail while going make-up free and donning a pair of trendy sunglasses to perfect her sunny style.  

She opted against wearing any accessories bar an extremely delicate necklace with a tiny 'K' pendant. Kendall also rocked a white manicure. 

In typical Kardashian style, Kendall ensured the outing was well-documented as she took to Instagram to share a smouldering selfie. 

She shared not only a selfie of her bikini body but also a duo of cosy snaps - one with Bella and another with Bella, Kourtney, Fai Khadra and one-half of DJ group Pizza Boys. 

While Kendall is living it up in the sunshine, her father Caitlyn Jenner is languishing Down Under on I'm A Celebrity... Get Me Out Of Here. 

The athlete - who Kendall and her sister Kylie still call dad despite her transitioning to female - is going down a storm with ITV viewers.

Last week, the stunners sparked speculation they are flying to Australia to support their dad Caitlyn. They boarded a private jet with Kylie's daughter Stormi, 21 months, on Wednesday and shared a slew of snaps to document the flight.

It is not yet known who will greet Caitlyn, 70, across the bridge upon her exit, but their flight comes a day after Kendall hit back at claims she wasn't supporting her dad during her jungle stint.

Taking to Instagram, Kylie, 22, shared a video of herself driving up to the private jet, before posting a sweet photo of Stormi gazing out of the window.

The make-up mogul also shared a snap of her pink Louis Vuitton bag and several views of the cloudy landscape. In one caption, she cryptically wrote: 'I love you'.

Kendall, 24, meanwhile, told her followers she too was embarking on a trip as she shared a photo of the plane and wrote: 'Kylie is coming to pick me up'.

It comes as sources told MailOnline it is not yet known who will greet Caitlyn over the bridge when she leaves the jungle.

Some of Caitlyn's fellow campmates' friends and families have already travelled to Oz ahead of the show's first live eviction. 

And after two weeks of silence, Kendall threw her support behind Caitlyn in an Instagram post, shared with followers on Wednesday evening.

Sharing an image of her father with campmates Nadine Coyle and Jacqueline Jossa, she wrote: 'Always rooting for you! Strongest person in the world.'
