Her older brother, Michael Cavallari, disappeared just days later, and his body was ultimately found two weeks later.Cavallari shared a New Year's post asking for "no extreme highs or lows this year." Unfortunately, last week's car crash, caused by another vehicle hitting hers, resulted in hospitalization.Cavallari and husband Jay Cutler are also parents to sons Camden and Jaxon.
