Singer/actress Marianne Faithfull is fighting the coronavirus in a London hospital.

The 73-year-old Brit, who famously dated Rolling Stone star Mick Jagger from 1966 to 1970, was admitted at the end of March (20) for pneumonia, and subsequently tested positive for COVID-19, according to a Facebook post shared by her friend, Penny Arcade, on Saturday (04Apr20).

The legend´s manager, Francois Ravard, added in a statement to Billboard.com: "Marianne is being treated for COVID-19 in hospital in London. She is stable and responding to treatment, we all wish her well and a full and speedy recovery."

Arcade insisted Faithfull is "not on a ventilator", but in an earlier post, revealed she had been in contact with Faithfull´s ex-husband, John Dunbar, who told her Marianne "can barely speak".

"She has withstood and survived so much in her life - including being Marianne Faithful (sic), that to be taken down by a virus would be such a tragedy," Arcade wrote. "I spoke to her last week and she was hiding out from the virus but she has caregivers..."

Faithfull made her name during London´s Swinging ´60s, having her first breakout hit with As Tears Go By in 1964, which was written by Jagger, fellow Rolling Stone Keith Richards and the band´s manager, Andrew Loog Oldham.

She was also close with The Beatles and sang backing vocals on their 1966 classic Yellow Submarine.

She later suffered from anorexia and drug addictions, and was homeless for a time.

Marianne released her 22nd studio album, Negative Capability, in 2018.

The news of her ill health emerges two months after Bohemian Rhapsody star Lucy Boynton was confirmed to portray Faithfull in an upcoming biopic.

Simply titled Faithfull, director Ian Bonhote´s new project is currently scheduled to begin production this autumn (20).
