Justin Bieber & Kourtney Kardashian 'Super Touchy Feely' As Scott Disick Stuns With Apology: New Year's Eve Battle

Kourtney Kardashian and Justin Bieber are happily hooked up, with eyewitnesses spotting them on dates and even a 4 a.m. exit from a hotel. But as Kourtney and Justin canoodle, her ex Scott Disick and his ex Selena Gomez are among those asking why. A new theory based on a recent Keeping Up with the Kardashians clip has emerged: Kardashian just wants to have fun in a light-hearted romance without stressing about dating, suggests Hollywood Take.

At 36, Kourtney has three children and an ex who also is the baby daddy. And although Kris Jenner is shown in the Keeping Up with the Kardashians clip attempting to persuade Kardashian to take on the attitude that she's single and ready to mingle, Kourtney made it clear that she's not interested in plunging into the dating pool.

So rather than kiss a lot of frogs in an attempt to find a prince (after all, Kardashian thought Scott was the one when he proclaimed himself Lord Disick), Kourtney was allegedly thrilled when Bieber proposed hooking up without a lot of strings attached and stress about long-term complicated commitments.

"I'm not a dating person," insists Kardashian in Keeping Up with the Kardashians. "I did the dating thing before Scott for like a minute, and it was so not for me."

The split between Disick and Kourtney occurred in the summer when photos of Scott canoodling with Chloe Bartoli went viral. That proof of PDA with another woman, combined with his passion for partying and alcohol despite repeated rehab visits, proved to be the final evidence to Kardashian that it was time to end her relationship with Disick. And she cites the time they spent together as additional evidence that a long-term commitment isn't something she wants or needs right now.

"I just got out of a nine-year relationship," she says. "I think the last thing I probably need is anybody in my life."

And that's where Bieber comes in as the perfect fun, flirty companion for Kardashian right now. The two have been heating up their hook-up for several months.

So does that mean the 36-year-old star of Keeping Up with the Kardashians is misleading the 21-year-old pop star and giving him hope the flirty affair has long-term potential? The Biebs is getting just as much out of the hot hook-up as Kardashian, sources told People.

"He has had a huge ego boost from hooking up with Kourt. It's been going on for a few months. He is used to being swooned by young girls that have nothing else going on. Kourt is a hot mom with a career. He brags about how hot she is. He is happy while it lasts. Even if she is using him to get back at Scott, he couldn't care less."

Another insider described Justin and Kourtney as "super touchy feely," while People's sources also revealed that although Disick is perturbed by the heat in the hook-up, Bieber doesn't care if some describe him as a rebound romance for Kardashian. The insiders also revealed that the affair has lasted for months thus far.

As for Scott, there's trouble ahead. Disick has planned a big New Year's Eve celebration in Las Vegas that's causing a bitter battle with Kourtney, a source told RadarOnline.

Scott urged Kardashian to join in in greeting 2016 at 10ak in the Las Vegas Mirage Hotel and Casino because he and Kourtney have enjoyed New Year's Eve celebrations as a couple for years. And her response to that plea is causing a war, according to Radar's insider.

"He told her that the only reason that he is doing this gig is because he could not stand to be at home while she goes out and has fun. But as of right now, Kourtney is not going to go with Scott to Las Vegas to support him," revealed the source. "Honestly, she wants nothing to do with this party."

Thus far, since he left rehab last month, Disick says he has stayed sober after the summer's long binge of substance abuse, cheating, and partying. But is it too little too late when it comes to the odds that Kardashian will leave Bieber to return to Scott?

"The prettiest smiles hide the deepest secrets. The prettiest eyes cried the most tears and the kindest hearts have felt the most pain," stated a cryptic quote Kourtney recently posted.

Radar's source said it was meant for Disick.

"She obviously wanted Scott to read this. She always said that he has the prettiest eyes and smile, which is why she chose him to father her kids," said the source.

However, Disick has tried to apologize, breaking down in tears, according to People.

A clip from KUWTK shows his attempt to express his regret to the Kardashians as well as Kourtney, stunning some with his tears.

"I'm sure you guys have heard a lot of horrible things about me that I should have been honest with, but I was too ashamed I was going to hurt everybody in this family, and not just her. I've apologized to Kourtney a hundred times but I've never apologized to like all of you for letting all of you down and embarrassing you guys," says a tearful Scott.

Moreover, Disick added that he takes ownership of his own responsibility for recovery, adding that he feels abandoned after having the Kardashians as a family who has his back to being dumped.
