Who Was Michael Cavallari? A Protective Big Brother
Michael Cavallari was Kristin’s older brother, born in June 1985, making him about a year and a half older than Kristin, who arrived in January 1987. The siblings grew up in a blended family dynamic after their parents, Judith Eifrig and Dennis Cavallari, divorced when they were young. Michael lived primarily with their dad in Laguna Beach, California, while Kristin spent time with their mom in Colorado and later Chicago before eventually joining the Laguna scene herself.
People who knew them described Michael as the classic big brother—protective, caring, and always looking out for his little sister. Throwback photos shared by Kristin show the two smiling together, capturing those carefree moments that define sibling relationships. He was single with no children at the time of his passing, and those close to the family noted his struggles with bipolar disorder, alcohol, and gambling, which added layers of complexity to his life. Yet, the love between brother and sister remained a constant thread. Kristin has spoken warmly about how Michael made her feel safe and valued during their split-family upbringing.

The news devastated fans and the Cavallari family alike. Kristin shared a heartfelt Instagram tribute at the time, saying her “heart is in a million pieces.”
The official ruling came months later: Michael’s death was accidental, caused by hypothermia after exposure to freezing temperatures following a car crash. Reports mentioned he had been dealing with paranoia in the days leading up, possibly linked to his mental health challenges. No foul play was involved, but the circumstances left the family with many unanswered questions and profound sorrow.
