Justin Bieber & Kourtney Kardashian Hookup & Baby Rumor Heat Up Social Media: Khloe Kardashian Beliebs

Kourtney Kardashian looked as hot as her hook-up with Justin Bieber when she attended his concert. Although Kourtney has sought to keep her romance with the pop idol under wraps, Kardashian finally came out of the shadows and made it clear that she’s a Belieber, noted the Daily Mail.

Rocking out with her friends Malika and Khadijah Haqq along with rapper Big Sean, Kourtney enjoyed the show, and she summed up how they all felt on Instagram.

“Beliebers,” confirmed the picture.

Some followers of Kardashian were not happy that she’s become involved with the 22-year-old.

“[L]eave Justin alone! Be ashamed of yourself for taking advantage of a kid! Your like 14 years older than him! Your a discusting slutty mother! [sic],” scolded one.

However, others defended Kourtney.

“[A]ll these people, they’re literally peasants and beneath you. Rock out,” encouraged another.

As for the rumors that Justin also remains involved in an on-and-off relationship with Hailey Baldwin, the model popped up at the concert as well.

But it’s Kourtney and the Biebs who have hooked up repeatedly over the months since Kardashian split from her baby daddy Scott Disick. The relationship between the reality TV star and pop star remains on the “close friends” level, according to Gossip Cop.

Kourtney and Justin have gone to clubs, and Kardashian even got an invite to his exclusive birthday bash, which she attended. But now it’s Khloe Kardashian who seems to have decided to go public and respond to the rumors about Kourtney and her 22-year-old boy toy.

Taking to Twitter, Khloe posed a question.

“Is there an age limit on being a belieber? #SeriousQuestion.”

With 19.5 million followers, Khloe got bombarded with hilarious comments about the known hook-up between Kourtney, 36, and the Biebs, 22, including those who couldn’t resist pointing out the noticeable difference in their ages.

All the tweeting about her sister entertained Khloe so much that she could not resist responding and even applauding the excitement over Kourtney’s famous romance as well as the humor, rather than denying it, hinting that she Beliebs the hook-up is for real.

Khloe Kardashian was entertained by questions about Kourtney Kardashian's hook-up with Justin Bieber.

“I am dying at all the replies telling me to ask Kourtney LOL,” Kardashian tweeted her followers. “YAAAASSSSS with the shady ways lol.”

And with impeccable timing, this happened almost at exactly the same time as when Kourtney was dancing her heart out at Justin’s concert. Kudos to Khloe for knowing when to throw out that zing in the Twittersphere.

As for the latest on Kardashian and the Biebs, rumors have been swirling that Kourtney is pregnant, as the Inquisitr reported.

However, Kardashian has faithfully been flaunting her flat fab abs on Instagram, and those contradicting the rumor are pointing to her bare body poses as evidence against the pregnancy reports.

And now, in what could be interpreted as another indication that no, there’s no baby bump blossoming, Kourtney joined Khloe and Kris Jenner on a wine-tasting tour that left all three ladies feeling the effects of the alcohol, according to the Mirror.

“Hungover wine tasting,” summed up Kourtney on social media.

Khloe mocked one of her sisters during the wine fest by using an app that distorts the face to enlarge her lips.

“[It’s the] Kylie Jenner filler,” proclaimed Khloe.

While Khloe had fun joking about lip fillers, a new lawsuit is no joke. It involves Khloe and Kourtney as well as their sister Kim Kardashian, reports People.

Although all three are famed for their use of social media to promote themselves and their brand, the lawsuit from Hillair Capital Management claims that the sisters are in breach of their contract because they failed to promote the Kardashian Beauty line.

The deal that the Kardashians and Hillair originally struck involved an agreement by the sisters that they would work to raise awareness of the beauty line, promoting and marketing it.

However, Hillair alleges that the Kardashian sisters failed to follow through with that agreement. And the price they’ll pay if Hillair wins is high even for a Kardashian.

The company is seeking over $180 million in the lawsuit for a variety of issues, including “fraud and deceit,” according to Ace Showbiz.

In addition, the investors are seeking to get back the $10 million they originally invested.
