Kourtney Kardashian Pregnant While Partying With Justin Bieber: Who’s Her Baby Daddy?

Justin Bieber and Kourtney Kardashian repeatedly have hooked up since her split from baby daddy Scott Disick last year. Most recently, Bieber, 22, and the Keeping Up with the Kardashians star, 37, continued their fun fling when he devoted part of his weekend to partying with Kourtney, according to Us Weekly.

A source told Us that Kardashian and Bieber reunited at a night club party, where they hung out together in a DJ booth. The night club, located in Miami, was the scene of a birthday celebration for club entrepreneur David Grutman, one of Kourtney’s pals.

Justin showed up at the nightclub at 12:30 a.m., heading first to the DJ booth to persuade the night club party-goers to croon “Happy Birthday” to Grutman. Bieber then demonstrated his dance skills by prancing around in time to his own music, revealed the source.

“At around 1 a.m. [Justin] disappeared for a few minutes only to reenter the DJ booth with Kourtney Kardashian in tow.”

And although she refrained from a public duet, Kourtney was observed making it clear she knows the lyrics to Bieber’s songs by mouthing along with the tunes.

But OK! magazine claims that her pals feel the mom of three has been “partying” too much since that breakup with Scott, noted Gossip Cop, which investigated the claim.

Kourtney’s friends allegedly are concerned that her “nonstop club-hopping” has gone overboard, with even “hard-partying baby daddy” Scott opining that she should cut back on partying.

“[Kardashian’s] out drinking until the early hours, then she sleeps in late, leaving the kids with the nannies,” alleged one source. “It’s shocking how little time she spends with her children these days… Everyone gets her wanting to have a little fun, but it’s now a near-daily thing, and her family life is starting to suffer.”

However, an insider told Gossip Cop that the claims of Kourtney abandoning her children and partying too much are “absurd.” And when the reality TV star does party, she enjoys herself only after devoting the day to her children.

But when it comes to those children, does Kardashian actually have another one on the way? Amid partying with Justin in a night club, Kourtney reportedly is pregnant.

In Touch revealed that Kardashian should be congratulated for “expecting baby No. 4 with on-again, off-again love, Scott Disick,” citing an insider who described the Keeping Up with the Kardashians star’s desire for a fourth child.

As to the explanation for how she could be pregnant with Scott’s child when she had split with him in July 2015? The insider contends that she did not want more than one baby daddy.

“Kourtney has always wanted four kids, but has been adamant about not wanting multiple baby daddies.”

The reality TV star’s family is described as “shocked” by the news that Kourtney is pregnant again, but the clan reportedly has accepted the blossoming baby bump. The source shared that Disick is doting on both his baby mama and children (Mason, 6, Penelope, 3, and Reign, 1).

“This baby may even get them back together!” added the insider.

As “proof” that she is pregnant, In Touch also shared a photo that Kourtney had posted.

“On a staircase,” Kardashian simply wrote for the caption.

“All eyes were on pregnant Kourtney’s baby bump!” proclaimed In Touch of the picture.

Life & Style‘s sources also claims that Kourtney is five weeks pregnant but alleges that no one knows whether Bieber or Disick is the baby daddy, describing Kardashian as in a “love triangle” with Justin and Scott.

“At first, everyone just assumed it was Scott’s since he’s been trying to make things work, but then out of the blue, she jets off to spend time with Justin,” revealed one of the sources. “Her close friends and even her sisters aren’t sure anymore.”

One of the sources revealed that Disick is no longer using drugs or drinking alcohol. However, observing Kourtney partying with Bieber is challenging, and he is hoping that he is the father of her fourth child.

“It’s heartbreaking for [Scott] to see Kourtney with Justin.”

Although a paternity test would answer the question, one of the sources revealed that Kardashian does not want to take the test.

“A paternity test is the only answer at this point, but it’s the last thing in the world she wants to do,” added that insider. “This whole thing has her stressed out like you wouldn’t believe!”
