Kourtney Kardashian allegedly turned down Scott Disick's marriage proposal

Kourtney Kardashian allegedly turned down ex Scott Disick's marriage proposal during her family's recent vacation to Costa Rica, Us Weekly reports.

Disick, who shares Mason, 7, Penelope, 4, and Reign, 2, with Kardashian, casually proposed to Kardashian a few days into the trip following his two-year attempt to clean up his act and win her back.

"Scott proposed to Kourtney," a source told Us. "Not with a ring. He just said, 'Let's get married.'"

Instead of giving into his charm, though, Kardashian "told him no," which left Disick feeling "embarrassed, upset and angry."

The former couple was staying at a rented mansion with the rest of Kardashian's famous family when the alleged proposal went down. To make things more embarrassing for Disick, it appears as though the moment may end up on TV, as the source claims that the "Keeping Up With the Kardashians" cameras were rolling when he popped the question.

To cope with the rejection, Us Weekly reports that he "covertly flew another woman" to the tropical locale and "holed up with her in the production team's hotel" before jetting off to Miami to hook up with two more models.

"Kourtney is not upset he's seeing other women," the source continued. "She's upset he'd disrupt the trip with the kids. If you're dating someone important, bring her to meet the family. Don't hide her."

"Kourtney is over being with him," the insider finished.

Before the tense moment, the pair had shown signs of a united front as of late, often being photographed together while out and about with their three children. He also frequently appears in Kardashian's Snapchats. Though it's clear that both want what is best for their kids, Disick seems to be the only one still holding a flame for his ex.
