The Grammy-winning 59-year-old singer shared a picture of himself in hospital in a Facebook post.
He explained: "Was in a serious accident at 12:50am this morning...passed out while driving on the highway. Totalled the car...hospitalised, going through a myriad of tests...but I'm alive!!!
"Lost consciousness driving...but two human angels followed my swerving car with their emergency blinkers onto stop traffic ....drove behind me until my car crashed into the middle concrete island.
"I remember none of it except those two angels pulling me out of the passenger's side of the crumbled totalled car...airbags deployed...crushed metal and fibreglass!!
"I AM ALIVE!!!!
"Somewhat mangled, stitches on left thumb, sprained wrist, hurt knee, but I'm still here! God and two angels saved my life! I owe them.
"I am still here by the grace of God!
"Thank you, Lord ... thank you!"
