In addition to designing jewelry, writing her forthcoming self-help book Balancing on Heels, and promoting a "natural" lifestyle by declining to vaccinate her children, Kristin Cavallari is—according to Kristin—active in her husband Jay Cutler's charitable foundation. She revealed this Kristin fact in an interview with Michigan Avenue magazine last year.

During the interview, Michigan Avenue asked Kristin about her work with charities. Kristin responded,

For a few years I was bouncing around doing a lot of stuff, and luckily I've never been personally affected by a major disease. Then I met Jay, who has Type 1 diabetes, so I decided to put all of my focus into the Jay Cutler Foundation, which he founded to help kids with the disease.

Luckily!

This has been 500 Days of Kristin.
