Although the couple - who have children Mason, two, and four-month-old Penelope together - have gone through rough patches in the past and even attended therapy together, Kourtney says they are in a great place in their relationship right now.
She said: ''Scott is a great dad and is very connected to both of our children. He and I are in a really good, happy place.''
And Scott believes having two children has really cemented his relationship with Kourtney.
He said: ''Having two kids is like, you couldn't be more legit. It's the real deal, Kourtney and I are Mom and Dad.''
Scott is smitten with the kids, even calling Mason his ''best friend''.
He told Us Weekly magazine: ''Mason is my best friend. I just got one of his little cars working - it's fun for me to get him into cars.
''Penelope is beautiful. I mean my son is my world and my daughter is my new world. It's pretty unbelievable starting a new chapter in your life.''
