Scott Disick is "on a mission" to win back Kourtney Kardashian

A source said: "Kourtney is very encouraged to see how much he has been trying."

Kourtney, 37, ended her nine-year relationship with Scott after she saw photos of him touching his ex-girlfriend Chloe Bartoli while drunk on board a yacht.

Since then, though, he has entered rehab in a bid to get his drinking under control and "to show Kourtney he's willing to change".

After spending a month at the Cliffside Malibu rehab center last November, Scott - who was previously known for his wild partying - has stopped drinking excessively.

A source told Us Weekly: "He's in better health and better spirits."

And while the duo have not officially reunited, Kourtney is reportedly open to the idea of having another child with Scott.

The insider shared: "Kourtney wants to have another baby."

This comes shortly after it was reported that the 'Keeping Up With the Kardashians' star is currently "very happy" with Scott and is considering rekindling their romance.

A source previously said: "She got screwed over by Scott so many times in the past. Kourtney is still protecting herself.

"She doesn't want to say that they are back together until she knows for sure that Scott is fully committed to his family. But so far so good. Scott has been amazing to Kourtney, and she is very happy."

Kourtney is also impressed that Scott has made the family his "number one priority".

The insider explained: "For a long time, it really seemed like Kourtney was completely over Scott. She was acting very disappointed. It seemed she would never take him back. Then Scott decided to turn things around.

"It was like he finally realised that he needed his family. For the past few months, Scott has been amazing. He isn't sober, but very well behaved. He has shown Kourtney that she and the kids are his number one priority."
