- Yoko Ono was married to Beatle John Lennon until his death in 1980
- She is 83
Ono was hospitalized in New York on Friday after experiencing "extreme flu-like" symptoms, according to her publicist.
"Her doctor thought it would be a good idea for her to get checked," her publicist Elliot Mintz said. He denied media reports that she suffered a stroke.
Her son, Sean Ono Lennon, shared more details in a tweet Saturday.
"Thanks again for everyone's concern," he said. " She's home and running about as usual. Just the flu in the end."
Ono, 83, was married to Beatle John Lennon until his death in 1980.
She has won two Grammys -- one as an artist and producer, and the other as a video producer.
This month, she is exhibiting "Land of Hope," which comprises 19 pieces of her artwork in Mexico City's Memory and Tolerance Museum. The interactive exhibit promotes peace.
