Kim and Khloe Kardashian have thrown shade at their sister Kourtney's ex-boyfriend Younes Bendjima amid allegations he was unfaithful.

Givenchy and Balmain model Younes spoke out on Tuesday (07Aug18) following his split from the Keeping Up with the Kardashians star earlier this week after photos surfaced of him cosying up to former Hooters waitress Jordan Ozuna, who was previously linked to Tyga and Justin Bieber.

In a message posted to his Instagram story, the 25-year-old claimed that the images had made him look like the "bad guy" and blamed the media for "failing him". But Kourtney's protective sisters Kim and Khloe weren't having any of it.

On a screenshot of the model's post uploaded to celebrity gossip account The Shade Room, KKW Beauty founder Kim commented: "Nice pics from your 'boys trip'," adding an emoji with an elongated nose.

In another screenshotted post, Khloe quipped: "Alexa play 'heard it all before' by Sunshine Anderson," referencing the popular virtual assistant from Amazon which can play songs on request.

Kourtney, 39, and Younes started dating in 2016 after meeting at Paris Fashion Week and had recently enjoyed a family trip to Italy with the reality star's three children from her previous relationship with ex-boyfriend Scott Disick.

But the star called time on their relationship earlier this week amid claims they had been arguing constantly since returning from the European trip and the pair have since unfollowed one another on social media.

The television personality is also said to be "upset" at the emerging paparazzi pictures but doesn't plan to publicly address the claims.

"Kourtney is upset but she is trying to focus her energy on other things and stay busy," an insider told Entertainment Tonight. "There was a huge chance they were going to get back together and they were working on things. But now that these photos surfaced, things are definitely over."

Meanwhile, another source told editors at ET that Younes and Jordan aren't romantically involved.
