Sharon Osbourne has recalled a furious bust-up with Piers Morgan - and how husband Ozzy forced her to heal their relationship.

Sharon and Piers' relationship has made headlines in recent months after she defended him after his controversial remarks about Prince Harry and Meghan Markle.

The pair have known each other for two decades, and Sharon told that while they're close friends, they've butted heads in the past.

One of these clashes even got physical after Sharon smacked the former GMB host across the face in public.

"We argue like hell; we had a punch-up once," she told The Daily Mail's You magazine.

She continued: "I slapped him in Mr Chow's [a Chinese restaurant in London's Knightsbridge].

"Then I go home and Ozzy, goes, 'Call him and apologise. Do it right now.' That was years ago. He'll be huffy with me for a day and then he talks to me. We don't agree about lots of things."

Sharon quit US chat show The Talk last month after her defence of Piers prompted a considerable backlash.

She had rowed with colleague Sheryl Underwood over Piers' remarks about Harry and Meghan's interview with Oprah Winfrey during his final GMB shows.

Among his coverage of the interview, Piers had cast doubt on the veracity of a number of claims made by the pair during the interview, including that Meghan had struggled with suicidal thoughts.

His opinions led to an on-air clash with colleague Alex Beresford, during which he stormed off set.

That evening - 9 March - ITV confirmed Piers would not be returning to GMB hosting duties.

And he has spoken out a number of times in his friend Sharon's defence, claiming that her sudden exit from The Talk was the price she paid for loyalty.

"One of the most difficult days of my career… Sharon went on Twitter immediately and defended my right to speak… she's a loyal friend and my god has she paid for that," he told Tucker Carlson during an interview on US television.

"It's disconcerting to see a good friend of mine taken down. Sharon was taken down very deliberately - all because she dared to tweet that I was entitled to my own opinion."
