Kourtney Kardashian Is Embarrassed for Scott Disick over 'Trashy' Hookup with Bella Thorne, Says Source

Kourtney Kardashian may be living that yacht life in Cannes this week, but she’s not on board with ex Scott Disick‘s recent poolside PDA session with Bella Thorne.

“Kourtney thinks that the idea of Scott and Bella dating is embarrassing, particularly because she’s so young,” a source tells PEOPLE of the Keeping Up with the Kardashians star’s perspective on pictures of her 34-year-old ex canoodling with Thorne, 19.

Adds the source, “She also thinks Bella is a little trashy so the idea of the two of them dating definitely bothers her a bit.”

That said, Kardashian isn’t lacking for companionship herself. She’s been spending time with 24-year-old model Younes Bendjima, and the source notes that Kardashian, 38, is able to “brush off” her frustrations with Disick because “she is doing her own thing and is keeping busy with her own new boy toy.”

Nearly two years ago, Kardashian and Disick split after nine years together when he was photographed cozying up to stylist Chloe Bartoli.

On Thursday, Disick was once again spotted having a very friendly reunion with Bartoli just one day after the Thorne photos surface.

“Scott’s trying to stick it to Kourtney because of her liaison with Younes,” an insider told PEOPLE of Disick’s behavior this week. “It’s him acting out. He’s spinning out of control because of all the Kourtney s—. It just sets him off because she’s rubbing her new relationship in his face and posting all those bikini photos.”

And while Kardashian isn’t shying away from flaunting her own flings, the first source tells PEOPLE she’s trying to keep everything in perspective.

Says the source, “She has been down this road with Scott so many times.”
