They broke up in 2015 and have both dated several people since.
The reality star, 37, confessed his insecurities to his ex in a teaser for this week’s episode of Keeping Up With The Kardashians, telling the beautiful brunette he was ‘annoy[ed]’ when he thought he saw her ‘flirting’ with someone.
Jealous: Scott Disick admitted he doesn’t like seeing ex Kourtney Kardashian ‘with another guy’ in a teaser for this week’s Keeping Up With The Kardashians
The duo, who were both single at the time of filming, sat down to chat on the sun deck of the luxurious Malibu beach house the family rented last summer.
Scott cut right to the chase and told Kourtney, whom he shares son Mason, 11, Penelope, eight and Reign, six with, that: ‘I feel like it annoys me when you flirt with this lifeguard.’
The mother-of-three seemed a bit surprised, telling Disick she was ‘definitely not flirting with the lifeguard.’
Nonetheless, Scott told his ex: ‘In my head seeing you around any guy bothers me.’
‘Around another human that I’m not flirting with?’ a shocked Kourtney asked.
He tried to guilt the Poosh founder for her behavior, telling her: ‘Maybe it’s just something, I don’t know. I feel like you’re a little flirty.’
Frustrated, she told Scott: ‘I’m not, I promise.’
Though she tried to dismiss his worries, Disick went on telling her: ‘Then it’s my insecurity that I feel like I just don’t like seeing you with another guy.’

His insecurities: Though she tried to dismiss his worries, Disick went on telling her: ‘Then it’s my insecurity that I feel like I just don’t like seeing you with another guy’
‘It hurts me when you’re with somebody else,’ he went on while Kourtney listened uncomfortably.
Scott then got very candid, telling Kourtney he used to fixate on her past relationships.
‘Waking up to, like, looking at pictures of you with this guy you were dating…it’s just unhealthy,’ he revealed. ‘It made me upset and sad, you know what I mean?’
But with Kourtney now single, Disick said ‘now I wake up with no real problems.’
‘I’m, like, carefree in a sense that I don’t have that, that used to take up a lot of space in my mind all day,’ he told his ex.
Scott realized that relief was probably temporary, however, saying: ‘The big fear is if you start dating again, then it goes back to that and I have to feel like a different way again and it’s just hard. It sucks.’
He suggested the pair try to figure things out, telling her: ‘I guess now that you’re single and I’m single and you haven’t been with somebody in a bit, either we figure out creating our own lives together or separately,’

Tough situation: In a confessional video, Scott broke down the situation, saying: ‘It’s definitely difficult that Kourtney and I basically spend 90 percent of our lives together’
In a confessional video, Scott broke down the situation, saying: ‘It’s definitely difficult that Kourtney and I basically spend 90 percent of our lives together, travel together, do everything together, see each other every day, and the only difference is at the end of the night we part ways and go and sleep in separate houses.’
‘This whole limbo state isn’t that cool anymore. And I surely don’t want us both to wake up and be 50 years old and doing the same thing.’
Since shooting both Scott and Kourtney have begun to date new people.
Disick has been romancing 19-year-old model Amelia Gray Hamlin while things have been getting hot and heavy between Kardashian and Blink 182 drummer Travis Barker.
And it doesn’t look like the relationship will be cooling down any time soon, with sources saying the couple’s chemistry is ‘off the charts.’
