Kristin Cavallari wants four children.

The former 'Hills' star is currently expecting her first baby with fiance Jay Cutler and says they are already planning more and may have another before they get married.

She told Glamaholic magazine: ''We're talking about the possibility of having another kid right away and then getting married so we can have two kids close in age. We want four kids, so we're thinking maybe have one more, then get married, then have two more but we'll see, it all depends on how the first one goes.''

Kristin - who split from NFL star Jay last year only for them to rekindle their romance months later - also said the couple weren't trying for a baby but were pleased when they found out she was pregnant.

She said: ''Your motherly instincts naturally kick in. We weren't trying to have a kid but we weren't not trying, we left it up to fate. I knew there was a possibility but I was really excited! Even if you are trying, just to see a positive result is shocking!''
