Kourtney Kardashian ‘Creeped Out’ By Scott Disick Dating Younger Model, Despite Justin Bieber Hookups?

Kourtney Kardashian reportedly doesn’t approve of Scott Disick’s relationship with younger model, Christine Burke, despite her relationship with Justin Bieber.

Although 37-year-old Kourtney Kardashian has been linked to Bieber, 22, since splitting from Disick, 32, last summer, a source claims the Keeping Up With the Kardashians star was “creeped out” by her ex-boyfriend’s PDA with Burke, 20, during a recent trip to Cannes.

“They might be over but it is still weird to see the father of your children make out with someone else, especially someone so young,” a source told Hollywood Life on May 16. “It kind of has been creeping [Kourtney Kardashian] out.”

Kourtney Kardashian dumped Disick last year after he was caught getting cozy with his ex-girlfriend, Chloe Bartoli, in the South of France. As Kourtney Kardashian cared for their three kids, Mason, Penelope, and Reign, in Los Angeles, photos hit the web of Disick and Bartoli enjoying a vacation with friends and their nine-year relationship came to an end.

Since their split, Kourtney Kardashian has reportedly been hooking up with Bieber, while Disick has been linked to a number of women.

Most recently, Disick was seen with Burke in Cannes, and according to a report, the couple may be living together, despite Disick’s frequent outings with other ladies.

“Christine has moved into Scott’s home,” an insider revealed to Life & Style in April, according to a report by Hollywood Life. “She only ever goes to her home to pick up clothes. She spends a lot of time sleeping in and wearing Scott’s pajamas and sweatpants.”

And while a live-in girlfriend may tame some, sources claimed Burke hasn’t been the best influence on the newly sober Disick.

“She has her friends over to party and hang out in the Jacuzzi, and some of them are only 17,” the source added. “Having Christine at his house has in no way slowed Scott’s partying.”

Following his split from Kourtney Kardashian, Disick entered a rehab center in Los Angeles where he remained for 30 days. However, rather than stay completely sober after treatment, Disick has chosen to return to drinking.

As for Kourtney Kardashian’s relationship with Bieber, their romance doesn’t appear to be serious.

“It’s been a deep flirtation for months. He’s obviously close to the family, and Kris [Jenner] is obsessed with him,” a source told People Magazine in December. “It’s just one of those things where it makes Kourtney feel good about herself. It’s not serious at all. This young guy is into her, he thinks she’s hot and she’s older. She just wants to have fun.”

A second source told the magazine that Kourtney Kardashian and Bieber had been “hooking up” for several months.

Kourtney Kardashian and Bieber were first faced with romance rumors in October of last year when they were spotted attending an event in Los Angeles and later shared a photo together on social media. Then, after Kourtney Kardashian was photographed making her way out of Bieber’s Beverly Hills hotel room in the wee hours of the morning, they appeared to take a break from one another, and Bieber began seeing Hailey Baldwin.

Although Bieber has been involved in an on and off romance with Baldwin for months, he and Kourtney Kardashian continue to spend time together, and in March, she labeled herself a “Belieber” during one of his Los Angeles shows.
