- Yoko Ono was married to Beatle John Lennon until his death in 1980
- She is 83
(CNN)Artist and activist Yoko Ono has returned home after being hospitalized with the flu, her son said.
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.
