Justin Bieber & Kourtney Kardashian Share Sexy Photos Amid Affair: Selena Gomez Romance Stars In New TV Series?

Justin Bieber and Kourtney Kardashian are reunited, with the unlikely couple heating up their hookup just as Kourtney turns 37. As for why Kardashian and Bieber, 22, are dating, they’re enjoying their mutual agreement that they won’t cling to each other but just have some flirty fun, according to People’s sources.

The romance between the reality TV star and pop star began after Kourtney split from Scott Disick, father of her three children, and since then, Kardashian and Justin have been “hooking up on and off.”

Justin Bieber has been enjoying his hookup with Kourtney Kardashian.

Kourtney and Bieber reunited late last month when he was in Los Angeles, and although the “Sorry” singer has met her children, the two don’t engage in flirtations when the little ones are around, according to one of the sources.

“They have hooked up a few times, including recently. It happens in L.A,” clarified the insider. “He has met her kids, but they don’t hook up around the kids. It’s on nights when she has help and is able to go out.”

Although Kardashian is busy raising the trio of kids (Mason is 6, Penelope is 3, and Reign is just 1-year-old), she’s relaxed when it comes to spending time with Justin, who is thrilled with his cougar love, added one of the sources.

“Kourtney is great. Justin thinks it’s cool that she is older and hot. She isn’t clingy and has her own life. There are no bad consequences for Justin to hook up with her. She is very easy going and just makes it fun for him to be around her.”

In addition, Bieber gets a “huge ego boost” from the relationship, revealed one of People’s sources.

But the pop idol isn’t neglecting his Beliebers, and Justin just posted an extremely sexy photo of his shirtless body, baring his fab abs for his fans.

Almost simultaneously, his gal pal Kourtney shared her own racy picture of her revenge body. And in true Kardashian style, Kourtney posed to flaunt her sleek physique, noted In Style.

The sexy photo was part of a series that Kourtney has been sharing during her birthday holiday in Iceland, where she’s been heating up the landscape with events such as swimming late at night with pals.

In her racy picture, Kardashian sports a black one-piece suit with cut-outs, and that daring derriere-featured pose gives a clue as to what Kourtney feels is her best asset.

As for revealing how Kardashian feels about Justin? Kourtney finally gave a clue to fans with a photo revealing that yes, she is indeed a Belieber.

But where does her baby daddy Scott Disick fit into the picture? Although he still hopes to rekindle his romance with Kardashian, Scott hasn’t changed his partying ways, pointed out Page Six.

The breakup between Disick and Kourtney occurred last summer after pictures circulated showing Scott canoodling with a woman during a holiday.

“Scott says he still wants to get back together with her, but hasn’t done anything to prove it,” an insider shared with Page Six. “Kourtney is over it. She knows she looks amazing and she isn’t putting up with any of his s—t.”

Disick even went to rehab again recently but still continues to drink and party, even turning to Kourtney’s sisters Kylie and Kendall Jenner to accompany him in his drinking at the Bootsy Bellows Estate at Coachella.

The insider also revealed that Kardashian has let Disick know he has to demonstrate he has changed. But thus far, Kourtney isn’t seeing any signs that her bad boy has reformed.

“Kourtney tells him if he wants her back, he needs to show how much he’s changed. But instead he’s out partying at Coachella and will complain to his guy friends about how many rules Kourtney imposes on him.”

In an apparent attempt to show some sort of improvement, Scott has steered clear of shots and drinks beer to avoid becoming “too wasted.”

Selena Gomez is executive producing a new show about her life.

While Kardashian is still steering clear of rekindling her romance with Disick, Bieber hasn’t let go completely of his off-again-on-again girlfriend Selena Gomez. Now his 23-year-old ex-girlfriend is going to produce a Lifetime scripted series drawn from her life. Among the featured elements is Selena’s romance with Justin, revealed Hollywood Life’s insider.

Teaming up with Kevin Spacey to serve as executive producer, Gomez will focus on her experiences, including what’s described as a “love interest,” added the insider.

“Selena’s Lifetime special will include a love interest, but he won’t be the focal point. Justin Bieber has been a huge part of Selena’s life, and can’t be ignored.”

The show is being compared to Mark Wahlberg’s Entourage.
