Kristin Cavallari was born to parents Judith Eifrig and Dennis Cavallari, as one of two children. Cavallari's reported brother Michael has recently been reported as missing after his car was found abandoned in Utah. Michael, 30, was first reported as missing on November 27, 2015. Michael Cavallari's laptop and cellphone were both found inside the car and the vehicle appeared to have hit a large rock on the side of the road. The car's engine was running and its airbag was deployed when the police came across it. Cavallari has responded to her brother's disappearance via Instagram, posting a childhood photo of herself with her brother. In the caption she wrote: I appreciate all the concern, thoughts, and prayers that have been extended to me and my family. We remain hopeful and I will share any news that we receive. I have such gratitude for all those that have shared their support. Now, the search for Michael Cavallari continues.
