UPDATE: Yoko's illness has been confirmed by her son, Sean Lennon, to be the flu. In a tweet, he noted his mom is now "running about as usual":
Thanks again for everyone's concern. She's home and running about as usual. Just the flu in the end. I may go get a flu shot now...— Sean Ono Lennon (@seanonolennon) February 27, 2016
Yoko Ono, Beatle John Lennon's widow, was rushed to the hospital Friday night on fears of a serious illness when she called her doctor to report that she was sick.
Ono, who just turned 83, was originally reported to have had a stroke, but her family cleared that up quickly, with son Sean Lennon tweeting "was NOT a stroke, just dehydration/tired. She is FINE." He added that the only stroke she had had was "a Stroke of Genius! :-)".
Ono's publicist, Elliot Mintz, reported to the New York Daily News that Ono was "doing just fine."
The multimedia artist still lives in New York's famed Dakota, the building to which she moved in 1973, and the scene of Lennon's murder in December 1980.
