Kristin Cavallari wants to get married before having any more kids.

While the reality TV star's fiance Jay Cutler wants four kids, Kristin - who gave birth to the couple's first child Camden Jack last month - would love to have another one in a year but only if they tie the knot first.

She said: ''Jay wants four kids. I can see us having another baby in a year but I definitely want Camden walking down our aisle first.''

The shoes designer got engaged to Jay in November 2011 for the second time.

The pair previously called off their engagement in July 2011, just three months after they had originally announced their plans to wed.

Although she is loving motherhood, Kristin admits she never expected to be a mom by the age of 25.

She told People magazine: ''I just didn't imagine being a mom this young but now I'm content and complete. Immense love changes your priorities immensely.''

Meanwhile, Chicago Bears player Jay, 29, is already seeing signs that their firstborn could follow in his sporting footsteps.

Kristin said: ''He pointed out right away how big his feet are! And his hands were massive - he'll sure be able to hold a football.''
