Yoko Ono's son says his mother has been released from a New York City hospital after being treated for flu-like symptoms.
Sean Ono Lennon said on Twitter Saturday afternoon that his mother was home and "running around as usual."
The 83-year-old artist-singer is the widow of John Lennon of the Beatles. She spent the night at Mount Sinai West Hospital in Manhattan. Her representative told The Associated Press that Ono went to the hospital Friday night on the advice of her doctor.
