It’s been almost two months since the world learned that Justin Bieber and Hailey Baldwin are engaged.

Together, the young couple has been navigating some pretty rough waters, as they deal with intense media scrutiny, the pressures of wedding planning, and of course, exes.

Just a few short months ago, Justin was still on the market, which means his last flings as a single man are pretty recent.

Obviously, Selena Gomez is Justin’s most high-profile ex, but she’s certainly not the only famous woman he’s slept with.

As fans will recall, Bieber dated Kourtney Kardashian last year, and it seems that despite the considerable age difference, the two of them formed quite a connection.

So perhaps it’s not surprising that Hailey was chagrined to learn that Justin and Kourtney are still in regular contact with one another.

“Hailey is very protective of her relationship and she has every reason to feel threatened,” a source close to the situation tells Radar Online.

“She’s saying that Kourtney better stay away from Justin, and she won’t hesitate to ban him from speaking to her altogether.”

It might sound like Hailey is being melodramatic, but she may have good reason to be concerned.

The insider goes on to say that Kourt would be ready “to go after Justin in a heartbeat, if she had the opportunity.”

Sounds like Justin should probably sever ties with Kourtney for the sake of his relationship.

But even though we’re dealing with the new and improved Justin here, it’s a safe bet that he won’t do that.

“Things between Justin and Kourtney were more serious than most people realized,” the source claims.

“Their physical compatibility was off the charts, and they even started to bond about religion.”

The insider adds:

“Justin was hugely attracted to Kourtney, and she was really smitten by him. They had a lot of fun together.”

A different source confirms that Justin and Kourtney are still in contact, but denies that

“Kourtney and Justin are on great terms, they still talk every once in a while but there’s nothing for Selena to worry about. Kourtney only has eyes for Younes Bendjima, she’s totally into him and only him,” an insider close to Kourtney tells Hollywood Life.

“She will always be fond of Justin, she thinks he’s a great guy, but there’s nothing romantic between them anymore, that ended when she got serious with Younes,” the source adds.

These days, Kourtney and Younes are broken up, but those who know Justin best say he’s fully committed to his relationship with Hailey,

Of course, in the past, he was fully committed to his relationship with Selena.

And we all know how that turned out.
