“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,” Ono’s son, Sean Ono Lennon, said on Twitter Saturday afternoon.

Though it was initially reported that Ono may have suffered a possible stroke, her her publicist later said she was suffering from the flu-like symptoms. 

Lennon gave updates on Twitter to assure fans his mother was fine.

It was not clear if Ono was alone at the time she was rushed to the hospital, CBS2’s Tracee Carrasco reported.

At Strawberry Fields in Central Park, fans worried for Ono’s welfare, 1010 WINS Roger Stern reported.

“I hope she’s okay, you know? At least she’s been seen to and looked after, so hopefully she’ll get better soon,” one supporter said.

Ono has lived in the Dakota since 1973. Her husband, John Lennon, was shot and killed in front of the building on Dec. 8, 1980.
