Ozzy Osbourne was gifted a special metal cross made from the World Trade Center rubble in the weeks following the terrorist attacks of 9/11.
The Black Sabbath frontman was staying at a New York City hotel when hijackers crashed two planes into the Big Apple landmark on September 11, 2001.
And to mark the 10th anniversary of the tragedy, rock matriarch Sharon opened up about her personal recollection of the events while hosting her TV show The Talk on Thursday, during which she revealed all about the prized possession Ozzy received from a team of courageous firefighters.
She said, "That morning we went downstairs for breakfast. The kids and I. And we're in the dining room and there was Mayor Bloomberg... And then all of these men came and whispered in his ear... And he went off... And then we go upstairs, (and we're) watching the news and then we see what the whole world saw.
"You can't take like, this, 'Oh poor me, I'm so scared.' I was blessed that I had my family with me. But it leaves you totally numb. And to think now... 10 years later, it's still going on because our men and women from all over the world, not just here (in America), are still fighting.
"I can remember the day that it happened; we went up to the roof of the hotel and we were looking down 5th Avenue. There was nothing. There was nobody. There were no birds. There was nothing. It was silent. And that silence is terrifying.
"We got out of New York... and drove back to L.A. And driving across the country it was unbelievable, just that same eerie silence."
But Ozzy couldn't stop thinking about the devastated people back on the East Coast and returned two weeks later to play a concert for the firemen and first responders - and his selfless act was graciously received.
She added, "They made him this cross, which is made of one of the girdles from the South Tower. And when they gave it to him, it was two weeks later, literally, this isn't an exaggeration, it was still warm (from the burning)."
