Rob Kardashian reportedly suffered a medical emergency and was at a California hospital for treatment on Wednesday night. Kris Jenner and her boyfriend, Corey Gamble, went with him, along with Kardashian’s estranged fiancée, Blac Chyna. He was hospitalized last December for complications of type-2 diabetes, after he said he’d stopped taking his insulin. “When I got out of the hospital, I knew I needed to make changes,” Kardashian said at the time. “Chyna and I had a really big talk and she told me that by having her cook for me, my diabetes would be gone.” Kardashian later announced that he no longer had diabetes.
