TV presenter and former X Factor judge Sharon Osbourne has revealed she has tested positive for Covid-19 and was in hospital for a "brief" time. 

Osbourne, 68, shared her diagnosis on Twitter, telling her fans she is separated from rocker husband Ozzy Osbourne, 72, while she recovers. Ozzy has tested negative for the virus.

She tweeted: "I wanted to share I've tested positive for Covid 19. After a brief hospitalisation, I'm now recuperating at a location away from Ozzy (who has tested negative) while The Talk is on scheduled hiatus.

"Everyone please stay safe and healthy."

The Talk is filmed in Los Angeles County, where the Osbournes live.

California is in the grip of a deadly wave of Covid-19 and much of the state is under a stay-at-home order.

Osbourne's diagnosis comes days after Carrie Ann Inaba, her The Talk co-host, also announced she had tested positive.

Inaba, 52, said she is "resting and taking care of myself" following the diagnosis.

Other celebrities to publicly announce a Covid-19 diagnosis include Tom Hanks and his wife Rita Wilson, Idris Elba and Breaking Bad star Bryan Cranston
