Kristin Cavallari will never return to reality TV.

The former The Hills star - who gave birth to her first child Camden with fiance Jay Cutler in August - said she would never want to star in a reality TV series again as she thinks it would destroy her family.

"My family is too precious to me. A lot of relationships and friendships I had during The Hills and Laguna Beach were ruined, so I would never risk that with my family," the 25 year-old said.

The fashion designer also revealed she has no plans to marry her long-term love Jay anytime in the near future as she wants their son to be able to walk down the aisle himself: "We've talked about maybe having another baby first so we'll see. I want Camden to walk down the aisle, so it will be a few years yet."

Kristin has been jogging, nursing and healthy eating and is only two pounds away from her normal weight following Camden's birth.
