Justin Bieber Romancing Other Women Makes Cougar Love Kourtney Kardashian Insecure: Why She Avoids Scott Disick

Justin Bieber and Kourtney Kardashian began dating soon after the Keeping Up with the Kardashians star split from Scott Disick, the daddy of her three children. Kourtney has been enjoying the not-so-secret hot hookups that the two have shared off and on for several months, multiple sources told People.

The unlikely affair cooled off for awhile but now has gotten hot once more, with Kardashian and Bieber meeting up last month amid his Purpose World Tour.

“[Kourtney and Justin have been] hooking up on and off for a few months now,” revealed one of the sources. “They have hooked up a few times, including recently.”

Bieber has even met her children (Penelope is 3, Mason is 6, and Reign is 1), but they date only when Kourtney has help at home so that they can go to hotspots such as nightclubs in Los Angeles, clarified the insider.

And while Kardashian is having fun with the flirtation, Bieber feels that she’s worth any backlash, added the source.

“Kourtney is great. Justin thinks it’s cool that she is older and hot. She isn’t clingy and has her own life. She is very easy going and just makes it fun for him to be around her.”

In addition, another one of People‘s insiders revealed that Bieber gets a “huge ego boost from hooking up” with Kardashian, who recently turned 37.

While the 22-year-old pop star is enjoying himself, Kourtney is experiencing some insecurity related to the way that he flirts with other women, according to a source cited by Hollywood Life.

With Bieber also hooking up with Hailey Baldwin, 19, and even romancing 23-year-old Selena Gomez recently, Kardashian is considering plastic surgery at 37.

“[Kourtney] wants to hold onto Justin,” explained the source. “With all the models half her age that Justin has been with, Kourtney is feeling insecure. She’s been working super hard on her body and she looks amazing, but she feels like she could look much younger.”

In particular, Kardashian is worried that as a result of her recent weight loss, she has skin sagging around her jaw and neck. As a result, although Kourtney doesn’t feel she needs a facelift yet, she is contemplating having a forehead lift and a neck lift.

“[Those procedures] will help her look 10 years younger,” added the insider.

Kardashian and Bieber recently were seen canoodling after one of his performances, and Kourtney is described as ranking Justin as the “best lover” she’s experienced.

Where does this leave Scott? Disick remains estranged from Kourtney in terms of any romance, as revealed in a sneak peek of the new season of Keeping Up with the Kardashians, reported the Daily Mail.

Since splitting in July, Kardashian has remained consistent in stating that she does not want to rekindle her romance with Scott. During one scene, Kourtney looked noticeably stressed as she attempted to avoid Disick’s hug.

“She’s a tough cookie you’re talking about here. I do trust her, she did run my life for eleven years,” pointed out Scott.

However, Kardashian consistently avoided Disick in the scene, then, in a “confessional” with the camera, revealed how she views her relationship with the father of her three children.

“When it comes to Scott, I’m not looking to get back together anytime soon,” emphasized Kourtney.

In terms of boundaries, Kardashian wants to keep their relationship casual and friendly but stressed that she is avoiding giving Disick any hope that they will get together again as romantic partners.

“I don’t have specific boundaries set, but coming to help him pick out stuff for his kitchen and his new house as a friend….I’m totally okay with that, and I don’t feel like I’m giving any false hope.”

Kardashian and Scott broke up after she saw photos revealing that he was canoodling with his supposedly former girlfriend Chloe Bartoli. Kourtney had repeatedly expressed outrage at Disick’s infidelity, partying, and drinking, and those pictures took her anger to the point of ending it permanently.

While Kardashian has been hooking up with Justin Bieber since then, Scott has played the dating field. Among the women he has dated are model Christine Burke and Australian model Megan Blake Irwin.
