She’s a member of Instagram’s first family and dating Australia’s most high-profile basketballer, so when Kendall Jenner posts a revealing selfie, you know it’s going to go crazy.

The 23-year-old posted a bathroom selfie with her older sister Kourtney Kardashian at what is believed to be a celebration for brother Rob Kardashian’s 32nd birthday at the weekend.

While she’s prone to a revealing shot, and drew a massive reaction after wearing a dress featuring two dangerously high slits to an Oscars party last month, the latest effort takes it to another level, with more than three million followers liking the post so far.

Jenner has been dating Australian basketball superstar Ben Simmons for months, appearing courtside at a number of his games with the Philadephia 76ers and recently making more public appearances as a couple.

Last week she confirmed things had become more serious by donning the point-forward’s No.25 jersey as she watched on during a game against the Indiana Pacers.

Jenner’s status as a fashion icon continues to grow, with Harpers Bazaar labelling her a genuine “supermodel-in-the-making”.

“Not only has she made waves on the runway, but her street style game has won her major points in our book,” the publication wrote.

“Jenner can make a head-to-toe black outfit feel fresh again, she can work a formal ballskirt effortlessly on the streets of Cannes, and makes matching sweats look like the chicest thing we've ever seen.”
