Kourtney Kardashian and Scott Disick have ''no time'' to get married because they keep ''popping out kids'', the 31-year-old television personality has said.

The 'Keeping Up With The Kardashians' stars - who have Mason, five, Penelope, two and one-month-old Reign together - have been an item since 2006 but Scott admits that they have no plans about tying the knot any time soon.

He said: ''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 that we're popping out kids.''

The 31-year-old former model has admitted that he's focusing more on being a father to their children than a partner to the 35-year-old television personality and is enjoying watching their youngest child reach a new milestone every day.

He shared: ''There's always so much in the beginning when they're that little. Every day is such a big milestone, 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.''

Scott also praised his two eldest children, revealing that they are being a great older brother and sister to the new arrival.

He told People magazine: ''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.''
