EXCLUSIVE: Kourtney Kardashian 'could not care less' about pics of Scott Disick cozying up to a model


Kourtney Kardashian appears unfazed by photos recently released of her ex-boyfriend and father of her three children, Scott Disick, packing on the PDA with a pretty brunette.

Just days after vacationing with Kourtney and the Kardashian-Jenner family in Costa Rica, the Daily Mail released images of the 33-year-old reality star getting straddled by a woman wearing a nude thong swimsuit, while in a hotel pool in Miami, Florida. In the images, the two are seen laughing, smoking and sipping what looks to be cocktails while hugging up on one another.

A source confirms to ET that the woman is 20-something model, J Lynne, whose real name is Jessica Harris. On Monday, she captioned a photo from a sunny location, with the caption: "And in the midst of the crazy, I am still at peace."

And in the midst of the crazy I am still at peace 🙏🏽 #thankful

"Kourtney could not care less that Scott hooks up with other girls. They are broken up," a source close to Kourtney tells ET. "There has been no chance of reconciliation for quite some time now."

Kourtney, 37, and Scott have not been a couple since the summer of 2015, though the two continuously spark reconciliation rumors by sharing photos of one another on social media. Just a few days ago, Scott shared a pic of his ex in a swimsuit tending to their youngest son, Reign, on a private airplane, presumably while on their vacation in Costa Rica. "Mom," he simply captioned the image.

Our source claims that Kourtney wasn't thrilled about Scott going to Costa Rica with the family, and says he's been partying more often lately. In addition to his trip to Miami, the source alleges that Scott also had some late nights at the Sundance Film Festival last week.

Despite Scott's apparent partying, the source adds that the former couple are good about raising their children -- Mason, 7, Penelope, 4, and Reign, 2 -- in an amicable manner. "Kourtney and Scott do an incredible job of co-parenting and truly are unmatched when it comes to putting on a strong front with the kids," the source explains. "They never discuss any of their issues in front of the kids."

As for their love lives, the source continues, "Kourtney is happy being single, and Scott still hopes he has a chance to get her back one day -- but the chances of that happening are pretty slim."

While Scott was lounging in Miami, Kourtney was sharing a bikini photo of herself with pal Stephanie Shepherd. "Honeymoon," she captioned the image.

Honeymoon.
