The Talk co-host fought back tears as she thanked her fellow panelists for their support.
“It’s good to be with you guys and to be with everybody here who is a family,” Sharon said.
She added, “Just to have this outpouring of positive reaction from everyone that watches the show and our friends — it’s heartwarming.”
Osbourne also revealed that her husband has no plans to stop touring and performing despite his diagnosis.
“We’re not gonna stop until Ozzy is back up there on that stage where he belongs,” said Sharon.
“It’s what he was born to do and that’s it,” she added.
