He was 58
An emotional Stern made the announcement today on his SiriusXM radio show.
Stern said Cirellas heart gave out Tuesday morning during a procedure as he was being treated for the lymphoma.
I just have been so sad and so angry, Stern continued.

He didnt take care of himself.
Lord knows I loved Ralph.
In fact, I came to think of Ralph as family.

Its just so stupid and its killing me Ill never hear that again.
He just said, F*ck that guy … you dont spend a second feeling bad about this.
He was just that kind of guy … Ralph was Team Robin.
In our final exchange, I shared a story about someone who called me lucky.
And they were absolutely right.
