Yoko Ono was rushed to Mount Sinai Roosevelt Hospital from her Manhattan home last night, Page Six reports. Although initial sources suggested that the artist may have suffered a stroke, her representative says she was admitted for “flu-like symptoms” and dehydration and will likely be released sometime today. According to tweets from her son Sean Lennon, Ono is “really fine.” She turned 83 and released a new remix album, Yes, I’m A Witch Too, just last week.

Hey guys it was only rumors from press: was NOT a stroke, just dehydration/tired. She is FINE. Thank you everyone for your concern @yokoono
