George Michael -- Airlifted to Hospital After Car Crash in UK

George Michael was airlifted to a hospital yesterday after reportedly sustaining a head injury in a single-car accident in England ... but doctors say he's expected to be OK.

According to the singer's rep, Michael was a passenger in a Range Rover that crashed on the M1 motorway (a huge freeway) at around 5:50 PM local time.

The rep says no vehicles were involved in the crash. It's unclear exactly what caused the collision.

A rep for the emergency response crew released a statement saying, "[George] sustained a head injury and following treatment, stabilisation and immobilization by land and air ambulance crews, he was flown to the hospital for further care."

Michael's spokesperson says the singer only suffered "superficial cuts" -- and was doing just fine.

So far, the driver of the Range Rover has not been identified.
