In case there wasn’t enough drama in the Kardashian clan, Kourtney K. and her former longtime love Scott Disick are now battling it out to see which one can bag the youngest hookup!

The 38-year-old showed up to this year’s Cannes Film Festival with her 24-year-old boy toy, Younes Bendjima, and the duo didn’t waste any time when it came to cozying up on their rented yacht.

But shortly after Kourt stepped out with the model, Scott was on a plane to France with his latest fling, 19-year-old Bella Thorne. The pair was spotted flying out of LAX on Monday with the actress’ sister, Dani.

Later, the new couple was photographed getting handsy by the pool, with the father-of-three reaching up to grab the former Disney Channel star’s boob.

A source told People magazine that Bella “really likes the attention” she’s been receiving since going out with Scott and that the duo are “having fun together — partying and acting very flirty.”

As Life & Style previously reported, Scott is bummed about Kourt’s romance with Younes, and is making drastic decisions out of jealousy. “Scott will do anything to sabotage Kourtney’s relationship, including showing up wherever Kourtney and Younes are hanging out together,” the insider revealed. “He’s also been asking around, trying to get some dirt on Younes so he can bring it back to Kourt and persuade her to dump him.”

The 33-year-old clearly hasn’t come to terms with the fact that he blew his chances with the brunette beauty during their recent family trip to Costa Rica. The reality star was caught sneaking a girl into his hotel room, despite the fact that he was vacationing with his three kids.

“I think after everything that’s happened here in Costa Rica, Scott knows it’s done,” Kourtney said at the time. “But just saying those words just lets both of us move on.”
