Presley Gerber, the 27-year-old model and son of supermodel Cindy Crawford and businessman Rande Gerber, died Sunday at a rehabilitation facility in California, according to records from the Los Angeles County Medical Examiner. The medical examiner’s office confirmed that an autopsy was performed, but further testing is required before a cause of death can be announced. A family representative confirmed the death and requested privacy during this difficult time.

Gerber, born in 1999 and raised in Malibu, California, followed in his mother’s footsteps with a successful modeling career. He signed with IMG Models as a teenager and debuted on the runway for Moschino at age 16. Over the years, he worked with prominent fashion brands including Calvin Klein, Burberry, Dolce & Gabbana, and appeared alongside his mother in a 2018 Pepsi Super Bowl commercial that paid homage to her iconic 1992 campaign. He also modeled with his sister, Kaia Gerber, and was described by his agency as an entrepreneur and inspired by both his parents’ careers.

Despite a life in the public eye marked by privilege and opportunity, Gerber openly shared his struggles with mental health and substance abuse. He documented his experiences through social media, including a “Mental Health Mondays” series on Instagram aimed at raising awareness and reducing stigma around addiction and mental illness. Earlier this year, he posted a video from Mexico describing his use of ibogaine, a psychedelic treatment pursued outside the U.S. for opioid addiction and post-traumatic stress, though it remains banned federally due to health risks.

Gerber’s challenges with addiction and mental health were well-documented. In 2019, at age 19, he was arrested for driving under the influence, an incident that coincided with growing public awareness of his personal difficulties. In the same period, he tattooed the word “MISUNDERSTOOD” on his face, a move he later addressed as reflecting his feelings of alienation. He later had the tattoo removed but continued to battle opioid addiction, at one point experiencing a near-fatal fentanyl overdose.

In interviews and public discussions, Gerber spoke candidly about his mental health, medication, and ongoing recovery efforts. His younger sister Kaia, a model and actress, recently highlighted how his openness has provided an important example within their family, which traditionally maintained private boundaries on such matters. “We have this absolute teacher, my brother, who says, ‘I’m gonna be very human for everyone,’” she told a fashion magazine.

Gerber’s parents, Cindy Crawford and Rande Gerber—who co-founded the tequila brand Casamigos, sold in 2017 for $1 billion—have not released further statements, beyond requesting privacy. Presley Gerber’s death has drawn attention to the ongoing challenges faced by those confronting addiction and mental health issues, even amid wealth and fame.
