The 31-year-old and Kourtney, 35, have been together since 2006, and wedding rumours have been pretty much constant.
But Scott has insisted that they don’t have ‘the time’ because of their three children.
They are parents to son Mason, five, daughter Penelope, two, and one-month-old Reign Aston.
Of the wedding rumours, Scott told People magazine: “If it’s not broke don’t fix it – we’re happy the way it is.
“I don’t even think we’ll have time to get married at the rate we’re popping out kids.”
Scott admitted he’s more than content with his growing family, watching his children reach new milestones every day.
He said: “There’s always so much in the beginning when they’re that little. Every day is such a big mile stone, but this is my third time so it’s just kind of a charm.
“You know it by now: the first one was scary, the second one was less scary, and the third one you’re like, I get it, I got a whole team over here.”
And Scott said Mason and Penelope are not jealous in the slightest of the new baby.
He said: “I really thought the other two would have been a drop jealous and truthfully they’re so accommodating and welcoming. I don’t think I could have been that way if I had a sibling.
“I cannot get over how much the other two have showed affection to the baby.”
