American supermodel Cindy Crawford said on Sunday that she and her family are "beyond heartbroken," a month after the death of her son Presley Gerber.
The 27-year-old model, the son of Crawford and businessman Rande Gerber, died on September 20 at a rehab facility in California.
"We are beyond heartbroken to lose our beloved son and brother," Crawford wrote in a post on Instagram on behalf of her family, alongside a black-and-white photo of him.
"We are so proud of how he showed up in the world, with kindness and vulnerability," she added.
Kaia Gerber, Presley's sister, also paid tribute to him on Instagram: "You know how much I loved being your sister. it has always been, and will forever be, my favourite thing about myself."
Born in California in 1999, Presley Gerber modeled like his mother and sister, making his runway debut for Italian label Moschino aged 16.
In recent years, he had spoken openly on social media about his mental health struggles and drug use.
