BREAKING: Presley Gerber, the only son of Cindy Crawford and Rande Gerber, has died at just 27, after years of openly sharing his struggles with mental health and addiction. His younger sister, Kaia Gerber, recently described her brother as an "absolute teacher" who wasn't afraid to show the world his human side. Presley once said that if sharing his own struggles could help even one person get out of the place he had been in, "that's all I need to do." His family is asking for privacy during what they call a "very difficult and painful time." Read more about Presley Gerber's life and his family's heartbreaking loss below:
