Radke announced his sobriety in 2020, but his struggles with partying and drinking were captured on his hit Bravo series. He's since opened up about reaching an all-time low and how he worked to overcome the problem.

"Watching season 4 back was probably the hardest season to watch back for sure, because it really leans into what I was struggling with is my drinking and my partying," he told Entertainment Tonight in January 2022. "I'm just so proud of the fact that I was able to accept that I knew I had an issue, but that acceptance takes some time."

Hubbard later said that Radke had navigated his sobriety with "strength" and "what seemed like ease."

"The fact that @carlradke has been so open, so vulnerable with his journey, readiness to take accountability, and so dedicated to his own personal growth .. he is inspiring to watch," she previously wrote on Instagram. "I love you baby!"
