Kylie Jenner stirs the pot as she poses with Kendall Jenner's close guy friend Fai Khadra for Diddy's 50th Birthday Party

He's been Kendall Jenner's friend for ages.

But it appears as though the tables have turned as Kylie Jenner, 22, took her sister's close friend Fai Khadra, 28, as one of her dates to Diddy's birthday party on Saturday evening.

The 'self-made' billionaire dressed up in a slimming black gown as she clutched onto her friend's arm while tagging her supermodel sister in the caption, according to the Daily Mail.

Kylie looked stunning in the black sequin gown with a high slit and a revealing neckline as Fai gave his best model pose for the camera.

The Kardashian forever date cleaned up nice in a black suit and white button up as he linked arms with the youngest Jenner. 

Rumors constantly swirl that both Kendall and Fai are dating, and while she has always shot down the suggestion, she now plays along. 

Recently, the duo stepped out as dates to Hailey Baldwin and Justin Bieber's wedding.

“We don't date he's just my date,” the cover girl shared in an Instagram photo of the two.

And shortly after in November, she stirred the pot once more by asking her followers if she should 'start a family' with her close companion.  

The post showed the only Kardashian-Jenner left to not have children of her own holding her older sister Kim Kardashian's sons Psalm and Saint.

Two of her best friends Gigi Hadid and Hailey Bieber were quick to hop on board the baby train letting Kendall know that they approve.
