Yoko Ono was hospitalized in New York Friday evening after falling ill with symptoms of a "serious flu," according to her rep.

The wife of the late Beatles singer John Lennon was taken to Mount Sinai West, formerly known as Roosevelt Hospital, just after 9 p.m.

"To the best of my knowledge, she had symptoms along the lines of a serious flu, and her doctor thought it was best that she would get a check-up at the hospital," said her spokesman, Elliot Mintz. "There is no stroke and there are no life threatening circumstances as has been described to me.

"It’s just an advanced case of the flu."

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