As reported by TMZ, renowned folk singer Joni Mitchell was rushed to a hospital earlier today after paramedics responding to a 911 call found her unconscious. TMZ says Mitchell was “alert” while being taken to the hospital, but she’s apparently still in intensive care. No one from Mitchell’s camp has released an official statement about her condition, so we still don’t know what caused her to fall unconscious. TMZ’s sources say the situation “appears to be quite serious,” though, so some comment is most likely forthcoming.
