Scott Disick would have another baby with his ex-partner Kourtney Kardashian, despite both of them now being in separate relationships.

The 34-year-old reality star - who is now in a relationship with 19-year-old Sofia Richie - already has three children, Mason, seven, Penelope, five, and Reign, two, with his former on/off partner, but has admitted he would be open to the possibility of expanding their brood once again, despite not being a couple.

When asked during Sunday's (05.11.17) episode of 'Keeping Up with the Kardashians' if the pair would have another child by close friend Malika Haqq, Scott said: "Yeah."

Malika then probed further by asking: "Wait, would you donate or is this like a strict you gotta lay it down?"

To which Scott added: "Whatever she wants but probably just do it like artificially just so it's like not weird."

Later, in a confessional, Scott admitted his "biggest focus" in life is his brood, and insisted it was "nice" not to have "false hope" that his relationship with Kourtney - who is now romancing Younes Bendjima - could take off again.

He said: "I definitely think that Kourtney's got a lot of built-up anger towards me, but at the end of the day, we have three kids together. That's not going to change. My biggest focus now is learning how to really, legitimately move on and think about doing a lot more with my kids without Kourtney. It's kind of nice in some sense that there's no more false hope. It's just another transition in a very weird part of being together and not being together."

Meanwhile, 38-year-old Kourtney admitted in a previous episode of the E! reality series that she would consider having another baby with Scott if the "situation was right".

She said: 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."
