Sean Kingston was "coughing up blood" and in "danger of drowning" after his jet-ski accident on Sunday (29.05.11).

The singer's rescuers Jonathan Rivera and Jimmy Vega were in a boat approaching Palm Island Bridge in Miami , Florida, where they witnessed the aftermath of the incident and revealed the 'Beautiful Girls' hitmaker was in a bad way when they reached him.

Jimmy told RadarOnline that Sean had a neck wound and was "extremely dazed and in danger of drowning" while Jonathan added to TMZ that the singer was "puking up blood and convulsing".

Although Sean was originally classed as critical when he was admitted to the Jackson Memorial Hospital after crashing into the bridge, he has now been moved from a trauma ward to an intensive care unit (ICU) where he is said to be stable.

A woman who was with Sean - real name Kisean Anderson - is now alert and talking to investigators.

Officers are said to have ruled out alcohol playing any part in the accident.

A statement from the Florida Fish and Wildlife Conservation Commission - which regulates boats in Florida waters - read: "Anderson was operating a PWC (personal watercraft) with a female passenger westbound along McArthur Cswy (Causeway) towards the Palm Ave bridge. Anderson struck the bridge and was transported to Ryder Trauma Unit in critical condition."
