Katherine Helmond has passed away.

My beautiful, kind, funny, gracious, compassionate, rock. You were an instrumental part of my life. You taught me to hold my head above the marsh! You taught me to do anything for a laugh! What an example you were!

Rest In Peace, Katherine. pic.twitter.com/HNIH0Ty6MN
