Yoko Ono Hospitalized in New York With Symptoms of 'Serious Flu,' Rep Says

The singer was taken to a hospital in New York for flu-like symptoms.

"It’s just an advanced case of the flu," Mintz added of Ono, who turned 83 on February 18.

Mintz said that Ono "hopefully will be released as early as tomorrow."

Following Mintz's explanation for Ono's hospitalization, her son Sean Ono Lennon took to Twitter. "Hey guys it was only rumors from press: was NOT a stroke, just dehydration/tired. She is FINE," read his first tweet. A second tweet read, "Only stroke @yokoono had was a Stroke of Genius! :-) She's really fine. Thanks for all the well wishes! Big Love, Sean."

Mintz confirmed those were among her flu-like symptoms. "Dehydration and feeling tired would fall under the umbrella of the flu," he said.
