10:26 AM PT -- A rep for Andrea says the singer hit his head during the fall but is back home and doing very well.
Andrea Bocelli had a scary fall off a horse in Italy ... and had to be rushed to a hospital by helicopter.
Bocelli was riding the horse Thursday near Pisa when he fell. It's still unclear how the accident happened, but he was airlifted to a hospital. One positive sign ... he tweeted to fans, saying, "I feel great. It was just a trivial fall from a horse."
The helicopter ride makes us think he's downplaying this somewhat.
