Kourtney Kardashian Has Kylie Jenner Spy On Boozing, Partying Scott Disick: ‘KUWTK’ Star & Justin Bieber Reunite?

Kourtney Kardashian split with her bad boy boyfriend and baby daddy Scott Disick last summer after repeatedly giving him another chance. Showing that she’s single and ready to mingle, Kourtney, 36, then hooked up with Justin Bieber, 21, for some flirty fun. But recently reconciliation rumors have swirled amid sightings of Kardashian up close and personal with Scott. Are those embraces just for the Keeping Up With The Kardashians cameras, while behind the scenes Kourtney continues to enjoy secret sessions with the Biebs? Or does her ex still have a chance?

Always ready to dish the dirt, sister Khloe Kardashian recently discussed the inside scoop on whether Kourtney is ready to date, as well as the truth about what she believes about the Biebs, reported E News.

Scott and Kardashian split last July. Thus far, their reunions have apparently been focused on the children, who include one daughter, Penelope Disick, 3, and two sons, Mason Disick, 6, and Reign Disick, 1.

While Scott has been seen with models, Kourtney has been repeatedly spotted with Justin. But is Kardashian dating the pop star? Khloe insists that Kourtney isn’t ready yet.

“I’ve been like, ‘Do you want to go on a date? Like, what do you want?’ ” said the 31-year-old sister of Kourtney. “She’s not thinking about that yet. You know, she’s so all about her kids, so all about, you know, ‘Let’s get also Scott healthy and in a good spot.’ ”

As for whether Bieber’s hooking up with Kourtney, Khloe carefully worded her response.

“Justin has been a friend of the family’s for years and years,” evaded Kardashian.

However, Bieber was somewhat more forthcoming in an interview reported by On Air With Ryan Seacrest.

“I’m being used, man. What can I say?” teased the pop star in response to the question of whether he and Kourtney have hooked up. “No, no, but for real, she’s great.”

However, Hollywood Life reports that Kardashian and Justin recently reunited. The 21-year-old pop star and 36-year-old reality TV star tried to keep it quiet by leaving their rendezvous separately.

But both Bieber and Kourtney were seen hanging out at Los Angeles hot spot The Nice Guy restaurant, leading to rumors that it wasn’t coincidental that they headed there on the same night at about the same time.

As for what Disick is doing while Kardashian plays coy about her romance, he has raised some concern with a return to his pre-rehab bad boy behavior. Most recently, Scott was seen gulping down beers and partying with models, reported Wetpaint.

Disick spent the entire evening at Up & Down, a New York City club, on Friday, and also partied at clubs the night before. That can spell bad news for the co-parenting agreement that he has with Kardashian. The arrangement requires that Scott remain sober and clean, and there to see it all go down at Up & Down was Kylie Jenner.

However, Kylie was there not just to join in the fun but to serve as a spy for Kourtney, a source told Hollywood Life.

Disick hosted a party at 1Oak, and Kardashian was so worried about how he might behave that she requested Jenner play an undercover role as eyewitness. After the recent sightings of Scott drinking booze and partying with models, Kourtney had a reason for concern, said the source.

“Kylie joined Scott and Tyga at 1Oak in New York on Kourtney’s orders,” revealed the insider. “She wanted Kylie to act as a spy and report back to see if Scott was as wild and out-of-control as has been recently said.”

Kourtney is not alone in worrying about Disick, whose closest friends are worried as well, added the insider.

“Scott has been drinking again, socially… he thinks he’s got a handle on it,” shared the source. “However, Scott’s pals don’t believe an addict should even be having one drink, especially since he’s so susceptible to his demons. They think he is rushing into his party lifestyle too soon after rehab.”

All this could mean problems when it comes to Kourtney allowing Disick to have unsupervised visits with their children. Moreover, her former bad boy boyfriend seems to be avoiding the entire Keeping Up With The Kardashians clan, skipping the Yeezy Season 3 show that the other members of the Kardashian family attended to support Kanye West in favor of partying, reported E News.

Disick spent the night with models partying until early the next morning. Although the playboy was not “too drunk,” an insider told E News that he did seem to be “high-strung” and, after exiting the club at 3 a.m., then went to an after-party in an apartment that lasted through to 7 a.m. Both family members and his pals are worried about all these signs that Disick has taken up the same habits that got him into trouble before with Kardashian.
