Ozzy Osbourne defends his wife Sharon Osbourne as 'the most unracist person'

Ozzy Osbourne is coming to Sharon Osbourne's side after a heated on-air discussion about racism on "The Talk" led to her departure from the show.

The daytime talk show went on a month-long hiatus in March and conducted an investigation that concluded Osbourne's behavior "did not align with our values for a respectful workplace."

Osbourne announced she was leaving the show March 26.

On Monday, her rock star husband spoke out about his wife on his Sirius XM show "Ozzy's Boneyard." He told his co-host Billy Morrison that a song on his upcoming album was about his wife and that she's "been through the mill of it."

"If my wife was slightly racist, I'll tell you she is possibly the most unracist person I've ever met," the 72-year-old singer said. "I'm not just saying that, you know?"

The "mill" Ozzy Osbourne addressed Monday started during a March 10 episode of "The Talk" in which co-hosts Sheryl Underwood and Sharon Osbourne got into a heated exchange. During the show, the 68-year-old TV host defended Piers Morgan's reaction to the Prince Harry and Duchess Meghan's tell-all interview with Oprah Winfrey.

Their conversation included the reason Harry and Meghan decided to step away as senior members of the British royal family, including Meghan feeling suicidal and not getting the help she felt was necessary from the palace, and someone (not the queen or the late Prince Philip, Harry later clarified) expressing concern about what color Harry and Meghan's son Archie's skin might be.

Osbourne said she felt she was "about to be put in the electric chair" because I have a friend who many people think is a racist and that makes me a racist," referring to Morgan, her former "America's Got Talent" co-judge, who said he didn't "believe a word" of what the royal couple said.

Underwood asked what Osbourne would say to people who felt it was racist to defend Morgan's comments during the controversial discussion. She replied: "For me, at 68 years of age to have to turn around and say 'I ain't racist' – what's it got to do with me? How could I be racist about anybody? How could I be racist about anybody or anything in my life? How can I?"

The next day on Twitter, Osbourne apologized. The show extended it's hiatus and days later some of Osbourne's former co-hosts, including Holly Robinson Peete and Leah Remini, accused Osbourne of racist behavior.

Ozzy Osbourne said his wife has "weathered the storm" and is "marching on."

"It's still unpleasant. Once you're accused of it people tie you with that brush and it's very hard to shake off," he said.

In April, "The Talk" returned without Osbourne. Underwood addressed the controversy saying it caused trauma and fear.

'The Talk' returns:Sheryl Underwood discusses Sharon Osbourne 'trauma' in 'race and healing' episode

Sharon Osbourne speaks out: After exiting 'The Talk' in racial controversy: 'I’m angry. I’m hurt.'

"I didn't want to escalate things with Sharon because I thought I was having a conversation with a friend, but also I knew I had to be an example for others to follow because I didn't want to be perceived as the angry Black woman," Underwood said. "And that really scared me. I didn't want to be that. I wanted to remain calm and focused. It is difficult to go back to that day because I just feel the trauma. I feel fearful a little apprehensive."

A week after the show returned, Sharon Osbourne appeared on HBO's "Real Time with Bill Maher" for her first TV interview since she left the show.

"I've been called so many things in my life, I am so used to being called names, but a racist is one I will not take," Osbourne said.

"Disagreeing with someone does not make you a racist," she added.
