The musician captioned the post, "Forever isn't long enough."
In the photo, the couple is seen not being able to keep their hands off each other, as they canoodled in front of the Eiffel Tower.
In the post, the Kardashian's sister was shown smooching her rocker boyfriend and holding hands while being on a carousel with the couple both sporting black-colored theme outfits.
Earlier this week, Kourtney's baby daddy made headlines after taking a jab at a photo of the couple being photographed on a boat in Italy.
Scott's resentful comment about the pair was caught in a screenshot that was leaked by Kourtney's other ex Younes Bendjima via the model's Instagram story.
Shortly after the leaked DM circulated, the Poosh founder seemingly retaliated by posting a picture of a cartoon image of a couple kissing with the caption, "HOW TO GET OVER SOMEONE who treated you badly a @poosh SPECIAL," in addition to the writing on the image that read, "Relax...this is going to hurt FOREVER.'

Just hours after Scott trashed the lovebirds with his jealousy, the paparazzi caught them on another make-out session during the duo's outing at Disneyland in Paris suggesting they were completely unbothered in his opinion.
Although, it was reported later that the father of three was allegedly regretful of his action and "mortified" by the incident.
"Scott is mortified that Younes shared his private DM message," an insider told E!News. "He had a low moment and was looking to someone who could relate to his feelings, and immediately regretted sending that message."
Despite all the drama, the Flip It Like Disick star's current girlfriend, Amelia Hamlin is reportedly 'standing by' his side after a source claimed that she had always acknowledged Scott's feelings towards his baby mama.
