The 'Beautiful Girls' singer - real name Kisean Anderson - is currently in stable condition following an incident on Sunday when a jet ski that he and a female friend were riding on collided with a bridge.
Suggestions that alcohol could have played a role in the accident have now been officially denied, according to an official Florida Fish and Wildlife Conservation Commission report obtained by TMZ.
The report details the events leading up to the crash: "Anderson was operating a PWC (personal watercraft) with a female passenger westbound along McArthur Cswy towards the Palm Ave bridge. Anderson struck the bridge and was transported to Ryder Trauma Centre in critical condition"
Kingston's 23-year-old female companion has been listed as "uninjured" in the Commission's official explanation.
Tennis star Serena Williams visited the popstar in his hospital room on Monday and later wrote about the emotional impact of Kingston's accident on her official Twitter page: "I am thankful that I have today. Tomorrow is not promised to any of us. I'm gonna make every day the best I can. #loveuSeankingston."
The 21-year-old singer's 'Eenie Meenie' collaborator Justin Bieber also tweeted to ask fans to keep his close friend in their thoughts, writing: "Got my friend @seankingston in my prayers tonight. a true friend and big bro. please keep him in your prayers tonight as well (sic)."
