Kendall Jenner upset with rumors that Kourtney Kardashian is having Justin Bieber's baby?

Justin Bieber & Kourtney Kardashian Pregnant Rumor Shocks Kendall & Kylie Jenner: Boozing Scott Disick Bombshell

Kourtney Kardashian and Justin Bieber have been linked as a couple since October. But has their hookup gotten so hot that Kourtney, 36, now is pregnant with 22-year-old pop idol Biebs’ baby? That’s the report, and Hollywood Life cites a source claiming that Kardashian’s sisters Kendall and Kylie Jenner are extremely upset.

At 20, Kendall has been linked to Justin in the past, and 18-year-old Kylie is joining her in feeling annoyed at the news that Kourtney is blossoming with a baby bump courtesy of the Biebs, claims the source. Both sisters also supposedly are baffled as to why Kardashian would want a fourth child.

“[Kendall and Kylie] won’t be happy about a Bieber baby at all. They already think Kourtney is addicted to having babies. They’ll just call her weird and desperate. But Kourtney is ready for their criticism.”

As for momager Kris Jenner, she is happy to have the pop star become a member of the Keeping Up With The Kardashians clan, according to the insider. And if Kourtney did have another baby with Justin as the daddy, Kris sees it as a ratings winner.

“No matter which daughter he’s associated with, she sees adding him to the family as a win-win situation. It means more exposure, which translates into more money for the Kardashians. Ratings would be through the roof for a show following Kourtney’s pregnancy with a Bieber baby,” pointed out the insider.

Not so thrilled is the Biebs’ ex Selena Gomez, who is already annoyed that Kardashian and Bieber have hooked up, claims the source.

However, Gossip Cop cites sources discounting that Kourtney is pregnant, noting that the rumors of a Biebs baby are coming from Life & Style.

“Kourtney’s Pals Say She’s… PREGNANT BY BIEBER!” gushes the Life & Style cover. “Justin can’t wait to be a dad.”

However, although Gossip Cop confirmed that Kardashian and Bieber began hooking up last autumn, sources say that the baby brouhaha is fictional and deny reports from insiders cited by Life & Style. Those insiders allege that evidence that Kourtney is pregnant with Justin’s baby come from her lack of contact with her baby daddy Scott Disick.

“Kourtney’s already admitted to friends that she and Justin have been intimate, and she hasn’t been with Scott [Disick] in a long time, so the math is pretty clear. It would have to be a Bieber baby.”

But one of Gossip Cop’s sources contradicted the reports by pointing to Kardashian’s slender body, and a Kardashian rep also was shocked at the rumors. A Bieber insider summed it up as “B.S.”

Meanwhile, Kardashian’s ex and real baby daddy, Scott Disick, is causing concern. After observing Scott engaging for weeks in his old partying and boozing ways, Kourtney is laying down the law when it comes to Disick spending time with their children, a source told Radar Online.

Kardashian met up with her ex and dropped a bombshell on him, telling Disick that he could no longer visit with his children without supervision.

“Kourtney needed to let Scott know he has messed up for the last time,” revealed the source. “She told him that she is now going after full custody and she will NOT allow her kids to be unsupervised with him ever again.”

Kardashian also informed her ex that he’s lost the hopes of reconciling romantically.

“Kourtney also let him know that he ruined all chances of ever repairing things with her in terms of a romantic relationship,” added the insider.

As to how Bieber feels about Kardashian needing to spend some time figuring out how to manage her children and her ex, he’s fine, a source told Radar.

Justin also is content with the request Kardashian made to keep their hookups away from the public view.

“Justin’s learned to keep his mouth shut because Kourtney made it clear she needs this to be discreet for the sake of her kids as well as the complicated situation that’s going on with Scott,” explained the source.

The pop idol and the Kardashian reality TV star have developed a friendship as well as a hookup that they both value.

“He loves having an older, experienced lover and they have a great friendship connection, too, so it works for both of them,” added the source.
