The actor’s brother, Christopher Coppola, announced the sad news on his Facebook page at the time, sharing that Vogelsang, a former modern dancer, died on May 26.
“In all of that painful emotional chaos she still managed to teach me something super important,” he wrote.
He continued, “Mama lioness looked at me deeply and said affection was a good thing and don’t let others embarrass me for being naturally affectionate.
Vogelsang shared Cage and Christopher, as well as son Marc, with August Coppola, the brother of famed director Francis Ford Coppola.
She went through these episodes of poetry – I don’t know what else to call it,” he said.
“I believe only a mama can truly teach that,” he wrote.
