"With the heaviest of hearts, we are devastated to share the news that our beloved Bobby Zarin passed away peacefully today surrounded by family after a courageous battle with cancer," his family revealed on Saturday. "There are no words to describe how heartbroken we are. Thank you, everyone, for all your love and support during this difficult time."
There will be a service for Zarin on Monday, but many of his and Jill's reality show friends have already honored him on social media.
