Kourtney Kardashian And Justin Bieber Secretly Dating As Scott Disick Surfaces With Mystery Woman?

Kourtney Kardashian and Justin Bieber are reportedly continuing to hook up in secret as Scott Disick appears to have embarked on a new relationship.

After a brief romance with Christine Burke earlier this year, Kourtney Kardashian’s ex-boyfriend surfaced with a mystery blonde at LAX on Sunday night, April 24, before heading to New Jersey, where he is expected to make an appearance in Atlantic City later this week.

In photos of Disick and his mystery girl at the airport shared by X17 Online, the potential new couple kept their interaction with one another friendly as photographers continued to snap pictures. Meanwhile, Kourtney Kardashian was in Miami with her family and her three kids with Disick: Mason, 6, Penelope, 3, and Reign, 1.

Kourtney Kardashian and Disick share three children together and dated for nine years before their summer 2015 split. As fans of Keeping Up With the Kardashians will recall, Kourtney Kardashian ended her relationship with Disick last summer after photos of him and his ex-girlfriend, Chloe Bartoli, in the South of France hit the web.

As Disick continues to be spotted with models around the country, a People Magazine report claims Kourtney Kardashian and Bieber, 22, have been “hooking up on and off for a few months now.”

Kourtney Kardashian and Bieber were first linked to one another late last year after her split from Disick. In October, the two began to spend time together in Los Angeles, but due to Bieber’s closeness to the family, no one thought much of their relationship at first. Then, in December, Us Weekly confirmed the two were hooking up — and had been since late August or early September, just weeks after Kourtney Kardashian’s split from Disick.

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

“[Kourtney Kardashian] is great. Justin thinks it’s cool that she is older and hot. She isn’t clingy and has her own life,” the source continued. “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.”

Another report regarding Kourtney Kardashian’s relationship with Bieber claimed their romance wasn’t serious.

“He has had a huge ego boost from hooking up with [Kourtney Kardashian]. It’s been going on for a few months,” a source told People at the end of last year. “He is used to being swooned by young girls that have nothing else going on. Kourt is a hot mom with a career.”

“He more thought, ‘Wow,’ and couldn’t believe that [Kourtney Kardashian] would go for him,’ ” the source said. “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… It’s just one of those things where it makes Kourtney feel good about herself. It’s not serious at all. This young guy is into her, he thinks she’s hot and she’s older. She just wants to have fun.”
