Kourtney Kardashian has admitted she would have another child with former partner Scott Disick if the "situation was right".

The 38-year-old reality star may have ended her relationship with the 34-year-old entrepreneur - who is now dating Sofia Richie - over two years ago, but she won't rule out getting back with him and having a sibling for their other three children, Mason, seven, Penelope, five, and two-year-old Reign.

Speaking on 'Keeping Up with the Kardashians' season premiere on Sunday Kourtney - who has been dating Younes Bendjima for around a year - admitted: "I feel like I would [have another baby with him] if the situation was right.

"But that doesn't mean, like, tomorrow, guys. So don't get any ideas."

Meanwhile, Scott recently admitted Kourtney is the "only person" he has ever loved, but they no longer have a "connection".

He said: "She's like the only person I've ever loved in my life. I think she's cute and stuff.

"There is no connection, she made that very clear just now. I just want everyone to know, we are just co-parenting."

Scott then jokingly added: "I try to f**k her like once a week."

And Kourtney admitted her former boyfriend's hard-partying and womanising ways have closed the door on them getting back together.

She said: "The debauchery that's gone on has definitely closed the doors several, you know, billion times."

Scott was then asked whether he conducts himself in a way that leaves open the prospect of them reuniting.

But before Scott could respond, Kourtney said: "He does for a time period. He can't be consistent."

The reality TV star then insisted his former partner secretly likes the bad boy aspect of his personality.

He said: "Here's the thing, every time I become too good of a person, she stops loving me because she fell in love with a guy who was a little bit f**ked up."

And when Kourtney refuted Scott's claim, he insisted: "100 percent! I treat you like royalty, you don't say hello to me. I spit in your face, you're like, 'Hey, babe!'"
