Artist Yoko Ono, the widow of the late former Beatle John Lennon, has been admitted to a New York-area hospital after complaining of severe flu-like symptoms, her spokesman says.
The 83-year-old’s official Twitter account on Saturday shared a link to a story which reported she had been hospitalised for a “possible stroke”.
However her West Coast-based spokesman, Elliot Mintz, denied US media reports that she had suffered a possible stroke or heart attack.
Mr Mintz said he understood the Japanese musician would be released from the hospital soon.
Ono had called her doctor, who said her symptoms sounded like the flu, and advised her to go to the hospital as a precaution, Mr Mintz said.
He said he did not know if she admitted herself or was taken by ambulance.
Sean Lennon tweeted to reassure fans his mother was “fine”.
“Just dehydration/tired… Thank you everyone for your concern,” he said.
Ono’s career as an artist has spanned more than five decades.
Last year, the Museum of Modern Art in New York marked her achievements with an exhibition of her early works, showing how her ideas influenced the development of art in the city in the 1960s.
Ono, also an experimental musician and film-maker, was once described by Lennon as “the world’s most famous unknown artist: everybody knows her name but nobody knows what she does”.
She and Lennon were married on March 20, 1969.
Lennon was shot to death on December 8, 1980, outside the famed Dakota apartment building just west of New York’s Central Park.
