The 'Sopranos' actor - who played Tony Soprano's father Johnny in flashback scenes in the drama series - has passed away at the age of 64 following a long battle with cancer.
His daughter Allegra Okarmus confirmed the news on Instagram alongside a number of family photos.
She wrote: "I was by his side when my dear father passed away this morning, peacefully, in his beloved Treehouse.
"We are both so lucky to be so intensely loved. I am so immensely grateful to have had him here on earth and I know that he hasn't gone very far.
"He had many credits, but his favourite one by far was that of Nonno Joe.”
Joseph's 'Sopranos' co-star, Garry Pastore, was the first to break the news when he shared a tribute to his friend.
He wrote: “RIP my dear friend, who fought an incredible fight. I will miss you. See you on the other side.”
