As you've likely heard by now, Justin Bieber and Hailey Baldwin are engaged.
Fans have come to reluctantly accept the reality of the situation, but that doesn't mean everyone is ready to congratulate the happy couple.
Among those who are reportedly not thrilled with the idea of the Biebs being off the market is none other than his former flame Kourtney Kardashian.
Kourtney and Justin dated on and throughout late 2016 and early 2017.
Actually, "hooked up" might be a more accurate term, as it's not clear if they were ever actually exclusive with one another.
Whatever the case, it seems Kourt has some serious regrets about allowing Justin to get away.
Earlier this week, we learned that Justin and Kourtney are still in contact, and quite understandably, Hailey is less than thrilled about it.
But according to sources close to the mother of three, Kourt has no intention of making as move on Justin.
But that doesn't mean she's not a tad envious of Hailey's situation.
“Kourtney isn’t trying to make any moves on Justin, she totally respects what he has with Hailey," one insider tells Hollywood Life.
"That doesn’t mean she’s not a little envious, and she can’t help but wish that she was the one engaged and madly in love."
The cause of Kourt's concern, it seems, is her growing anxiety over whether or not she'll ever find the right man.
Kourtney broke up with Younes Bendjima recently, and now, she's apparently concerned that she'll be a single mom for the rest of her life.
“She’s starting to fear she may never get married," says the source.
"Kourtney worries that maybe she’ll never find the one, or have her own big wedding and happy ending. So in that respect, she is jealous of Hailey and Justin,” the insider adds.
“But, there’s no need for Hailey to worry — Kourtney would never do anything shady to get between her and Justin.”
We're sure that's a load off Hailey's mind.
Now she just has to worry about the other 40 million women who want to bang Justin.
