One month after reports circulated the 39-year-old mother of three broke up with Younes, a source revealed they are giving their relationship another go.
"There was some miscommunication" but "they worked it out and are giving it another shot," the source toldUs Weekly, adding that the 26-year-old model "is a really sweet guy."
People reported in early August that Kourtney was the one who initially decided to plug the plug on their two-year romance, and an insider said at the time things "didn't end well."
The breakup came shortly after photos surfaced of Younes getting cozy with former Las Vegas waitress Jordan Ozuna in Mexico.
Younes, however, reportedly denied any wrongdoing on his part, writing in an Instagram story, "They really want me to be the bad guy. F-ck your Hollywood bullsh-t, can't have fun with your friends no more."
But Kourtney and Younes' relationship was already rocky by that point.
In July, the pair took a romantic three-week European vacation together but Younes appeared to criticize Kourtney on social media when she shared a sexy photo of herself in a floral thong.
"That's what you need to show to get likes?" Younes asked in the comments section of Kourtney's Instagram photo, although the post was subsequently deleted.
"He never liked that she posted sexy pictures of herself on social media. He doesn't want his girlfriend to do that," said the People source.
"He gets that it's her job, but wants her to post more covered-up pictures. He has always had a problem with this. This is the stuff they argue about and what made them split in the past."
Kourtney and Younes reportedly met in Paris in October 2016. Younes, who is Algerian and speaks fluent French, acted as a translator for the reality TV star's family after Kim Kardashian was robbed at gunpoint.
The couple went public with their romance in May 2017, and things got more serious in subsequent months as they traveled to the south of France, Egypt and Paris.

By December, an insider told People things were "definitely" serious between Kourtney and Younes.
Prior to getting involved, Younes reportedly dated model Jourdan Dunn, and Kourtney was wrapped up in an on-again, off-again relationship with the father of her kids, Scott Disick, for nearly a decade.
