What do you do when your bestie hooks up with your older sister’s ex-lover?

That was the dilemma facing Kendall Jenner recently. And her solution? Organinsing a girls’ night, naturally!’

After her reported fling with Justin Bieber’s, Kendall’s older sis Kourtney Kardashian was shocked to hear that the singer had already moved on by transitioning his long-time pal Hailey Baldwin out of the friend zone.

Biebs, 21, shared an intimate snap of the pair getting hot and heavy during their New Year’s holiday – and, apparently, Kourt, 36, was super unimpressed!

But Kendall Jenner, 19, has stepped in to make sure that her BFF Hailey, also 19, and Kourt get along by organising a girls’ night so they could kiss and make up.

According to a source, ‘Kendall didn’t want Justin coming between her sister and her best friend, so she convinced them to bury the hatchet.’

Happy birthday Kenny ????????

The three ladies got dressed up for a night out on the town and decided to let any bad blood between them go, as they partied with Kendall.

Very mature ladies! We just wonder how Justin feels about this new friendship?
