Kristin Cavallari is ''done'' having more children.

The 'Very Cavallari' star is happy having three kids - Saylor, two, Jaxon, four, and Camden, five, with her husband Jay Cutler - and wouldn't want to add to her brood anymore as she feels her family is ''complete''.

She told People Now: ''I love having three kids. I especially love having two boys and a girl - we feel like a very complete family. We're good, we're done. My daughter is two and a half and I don't have to lug around a diaper bag anymore and all the c**p. We're finally at a really good place where we can just pick up and go. All my kids have a little bit of independence, and we're just in a really good place. I don't want to go back to the diaper phase and all of that.''

And Kristin ''can't imagine'' having anymore children.

The 'Hills' star said: ''We're done. We are done. I can't imagine having another one. We just feel like such a complete family - I got my girl. Everything is just so great with it right now, why rock the boat? Saylor's more me. She can be a little bossy. She likes a good tutu here and there so she has that girliness in her but because she's always with her brothers, she's not afraid to get dirty, which I love. She takes after her mama but everyone's kind of a good mix of the two of us.''

The 31-year-old television personality is adamant she won't let her kids star on a reality television show.

Asked if she sees herself returning to similar series in the future, she said: ''I'm open to it, Obviously, the three of us come from similar backgrounds. The 'Hills' was a unique experience. I wouldn't trade it for the world ... To go back to that now as a mom and a wife, it would have to be different. I would have to be an executive producer. I would have to have more control and it would have to be more on my kind of terms. I would never put my kids on a reality show.''
