The 'Keeping Up With The Kardashians' star - who has Mason, six, Penelope, four, and 23-month-old Reign, with the 33-year-old model - is considering getting back with the father of her children if he shows he is "fully committed" to their family.

A source 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."

And the 37-year-old television personality has been impressed with how Scott has made the family his "number one priority".

An insider added: "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."

Meanwhile, Kourtney is said to be pleased with Scott's new-found attitude and excellent behaviour and the pair are back living together now.

The source told People magazine: "Kourtney seems very happy. She always loved Scott. They are living together now and are very happy. It's all about family time. Scott seems very happy about being back with his family. They are spending Thanksgiving together as a family."

The family will be spending Thanksgiving at Kylie Jenner's home after Kourtney revealed her younger half-sister will be hosting the family's annual get together.
