Kristin Cavallari says motherhood has helped her figure out her purpose in life.

The 'Very Cavallari' star loves being a mother to Camden, five, Jaxon, four, and Saylor, two - who she has with her husband Jay Cutler - and she says it is a ''great feeling'' knowing she's figured it all out.

She said: ''In my early 20s I was a mess, and I was just trying to figure it all out. But now, being married and being a mom, I know I'm where I'm supposed to be. And it's a great feeling.''

And the blonde beauty admits she was a completely different person when she appeared on MTV's 'Laguna Beach' at the age of 17.

She added: ''I didn't know what I was getting into [back then]. I was just going about my life and doing what producers were asking me to do. When I saw the first season, I was devastated about how I was portrayed. I came across as terribly bitchy. And I also felt as though my real-life boyfriend [Stephen Colletti] was being put in situations he normally wouldn't have been in. They were making it seem like there was this love triangle [with costar Lauren Conrad].''

And the 31-year-old television personality is excited about returning to reality television with her new series, 'Very Cavallari'.

She told People magazine: ''I wanted to get back in to reality, but not have the focus be too heavy on me and my family. So this was the perfect way to do it ...

''I'm working with people who really value my creative direction and think that I bring something to the table. I'm more confident than I've ever been before.''
