It was a special night for Cavallari. The Carousel of Hope gala benefits the Children’s Diabetes Foundation, which has personal meaning for Cavallari and her husband, Chicago Bears quarterback Jay Cutler.

“Jay is actually a diabetic, so any involvement I can do, I’m always going to jump on,” she told ET Online.

A host of celebs joined Cavallari at the glamorous charity event, including Sharon Stone, Denzel Washington, Jamie Foxx, master of ceremonies Jay Leno and the guest of honor, Sidney Poitier.
