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.
