Justin Bieber & Scott Disick Date Same ‘KUWTK’ Stars Kendall & Kylie Jenner Plus Kourtney Kardashian?

Justin Bieber and Scott Disick reportedly have something in common. Each “bad boy” has dated his way through the Keeping Up with the Kardashians (KUWTK) sisterhood. Scott and Kourtney Kardashian, for example, split last July, leaving Kourtney free to hook up with Justin. But has Disick moved on and joined Bieber in adding both Kendall Jenner and Kylie Jenner to his dating history list?

Scott had been steering clear of Kylie. But after Jenner split from Tyga, Disick reportedly made his move on the 18-year-old, according to a source cited by She Knows.

Kylie and Scott began partying together soon after her split, with some speculating that there was a connection between the two that went beyond friendship.

“She ran back into Scott’s arms after breaking up with Tyga, and people think they’re hooking up,” clarified the source.

Although Disick and Kourtney were together for more than nine years and have three children, he hasn’t hesitated to have friendships with the other KUWTK stars since he split from his baby mama, pointed out the insider.

“No one would be surprised if Scott and Kylie went public with their relationship. This family has no boundaries.”

And it’s not just Kylie. Kendall and Disick were seen “packing on the PDA” recently, claims OK! Magazine, which quoted a source describing their relationship. Jenner and Scott were holding hands on their way to a yacht party in Cannes, France, this month, and the source alleges that the two have become increasingly close.

“Scott’s feelings towards Kendall have developed in recent weeks. [They] have this connection.”

Kendall and Disick are not “secretly hooking up,” however, according to the International Business Times.

Despite some photos showing that Jenner and Disick were holding hands while getting on a boat, the evidence that they are close doesn’t mean they’re actually romantically involved. Instead, the 32-year-old ex-boyfriend of Kourtney was described as merely giving the 20-year-old model a hand onto the boat.

And while Kourtney and Scott have ended their relationship, Bieber and Kardashian are heating up their own hookup. However, the 22-year-old pop star and Kourtney have tried to keep their relationship confidential.

Justin at one point was seen partying with Kendall as his date despite his undercover romance with Kardashian, pointed out the Daily Mail.

However, even though Jenner was hanging out with Bieber, it was Kourtney with whom he has become “touchy feely.” Kardashian has met up with him at nightclubs, and she also was spotted attempting to sneak out of the Beverly Hills hotel where he was staying at 4 a.m. one morning.

“He and Kourtney were nearly inseparable – smoking on the patio together and were super touchy feely,” revealed an insider cited by the Daily Mail.

But while he now is with Kardashian, the Biebs at one point supposedly did date Kendall, according to a source quoted by Hollywood Life.

Even more awkward, he was with Jenner prior to his split from Selena Gomez, which left the “Hands To Myself” singer heartbroken, according to that source.

“When Selena and Justin were still a couple, Selena showed up at his house and walked in on him and Kendall in bed together, fooling around.”

And just like Scott Disick, the Biebs also has been linked to Kylie. However, Jenner has been open about her relationship with Justin, noted the Daily Mail.

“I’m so close to him because I feel like he’s been through exactly what I’ve been through in a completely different way but very similar,” explained Kylie. “He gets me, and every time I see him he always sits me down and is like, ‘Are you OK? You’re amazing. You can get through this, just stay true to yourself.’ He helps me a lot.”

Bieber also has defended Jenner.

“I want people to be more kind to young celebrities,” he urged. “Like Kylie [Jenner]. Look at her world, she has been living on TV since she was a kid. Every time she’s looking around she sees a camera and that’s affecting how she’s thinking and how she’s perceiving people and why she has to do certain things.”

As for reports that Justin and Kourtney have taken their romance to the point of pregnancy? Gossip Cop notes that despite rumors that Kardashian is blossoming with a Bieber baby bump, Kourtney is not expecting another child.

When Kardashian was seen in a one-piece swimsuit rather than a bikini, the false report speculated that it was due to her pregnancy. However, Gossip Cop describes that baby bump rumor as “not true.”
