Kim Kardashian Upset Over Kourtney Kardashian-Justin Bieber Hook-Up

Kim Kardashian is not sticking up to her sister Kourtney Kardashian after news leaked that she’s hooking up with Justin Bieber. Kim is less than thrilled to hear that her older sister has been hooking up with the Canadian pop star.

Reports claim that Kim Kardashian is not too crazy over the news. In fact, she has reportedly called Kourtney names because of it, an alleged inside source told Radar Online.

“Kim has told Kourtney she’s a disgrace and it’s lame and disgusting. Kim has been begging Kourtney to think of the kids instead of constantly trying to get back at Scott Disick with all these ‘look at me’ outings and sleazy late nights with Justin and other young kids.”

Kim isn’t just furious over this shocking revelation, she finds it “gross” and “disgusting.” She never in a million years expected this kind of behavior “from her big sister, of all people,” the insider added. Kourtney is usually the sensible one who focuses on her three children, Mason, 5, Penelope, 3, and Reign, 8 months, but it looks like this busy mom wants to have a little fun these days.

Kim Kardashian isn’t the only one who’s not a fan. Kourtney’s little sister, Kendall Jenner is also grossed out to learn that she’s been hooking up with the Biebs. It’s been rumored that Kendall and Justin used to hook up around the same time he was dating his famous girlfriend Selena Gomez. The rumors started when the two stars were then seen getting cozy once again at the Coachella Arts & Music Festival earlier this year.

According to the Hollywood Life, Kendall finds the situation weird and disgusting, and wishes for Bieber to stop sleeping with the rest of the Kardashian-Jenner clan.

“Kendall thinks the whole thing between Kourtney and Justin is weird. It’s just creepy. First off, Justin is Kendall’s good friend. He used to date her best friend Hailey [Baldwin]. Plus, he’s just too young for Kourtney.”

“He’s a complete player and for the life of her, Kendall doesn’t understand what Kourtney and Justin have in common. They both downplay their flirting with each other when they’re around Kendall, but she’s not an idiot. She knows something is brewing between them, and it’s just bizarre to her.”

According to a TMZ report, Kourtney is denying any romantic involvement with Justin. But sources close to the “Sorry” singer claim that the two have been hooking up for the past four months, which has also made Kourtney’s ex-boyfriend, Scott Disick, very upset. He’s also not happy to hear that the two are hooking up.

Earlier this month, it was rumored that the Biebs is not only hooking up with Disick’s ex, but he’s also been throwing shade at the Lord on his Instagram page. It all started when he shared this photo of himself up against a mystery girl, which his fans assumed was Kourtney Kardashian. He also included the infamous caption: “Lord knows.”

It turns out that Justin’s mystery girl was a blonde Instagram model who goes by the name Jasmine Villanueva. He’s been seen partying with the girl on a yacht.

An alleged source told the Hollywood Gossip that Scott has been doing his best to sober up and get his priorities in order for the sake of his family. Now he finds it’s hypocritical to learn that Kourtney has been partying and hooking up with various young men around town. He also thinks that it’s an unfair double-standard since he’s been treated harshly for his own hard-partying ways.

But it’s clear that Scott Disick has a substance abuse problem, whereas Kourtney Kardashian has been on the straight and narrow for several years.
