Sean Kingston is "breathing on his own" after being hospitalised following a jet ski accident last week.

The Beautiful Girls singer is no longer breathing through a tube and also walked for the first time yesterday since he ploughed into the Palm Island Bridge in Miami, Florida, leading him to be admitted to the Jackson Memorial Hospital with a broken jaw, fractured wrist and water in his lungs.

A representative for Sean said: "Sean is breathing on his own and walked for the first time this morning. Sean Kingston continues to be hospitalised at Jackson Memorial Hospital in Miami. His condition has been upgraded to serious.

"Sean thanks his friends, family and fans for their outpouring of prayers and well wishes."

Celebrity fans of Sean, real name Kisean Anderson, have been tweeting their support for the 21-year-old during his hospitalisation. Rihanna wrote: "Sean we praying for u baby (sic)."

Justin Bieber, who collaborated with Sean on his track Eenie Meenie, had earlier added: "Got my friend Sean Kingston in my prayers tonight. A true friend and big bro. Please keep him in your prayers tonight as well (sic)."
