"Sean Kingston is now stabilized and has moved from the trauma unit to ICU," Kingston's publicist, Joseph Carozza, tells E! News. "Sean's family thanks everyone for their prayers and support during this time."

Florida Fish and Wildlife Conservation Commission spokesman Jorge Pino said Kingston, 21, was operating his watercraft in the McArthur Causeway around 6 p.m. Sunday, when he struck the Palm Island Bridge. He was transported to Ryder Trauma Center in critical condition. Alcohol was said not to be a factor.

While the extent of Kingston's injuries has not been released, TMZ quoted an off-duty Coast Guard member who happened to be on the scene shortly after the crash and helped pull Kingston (whose real name is Kisean Anderson) from the water saying the performer was coughing up blood.

The unidentified 23-year-old female passenger was listed as being "uninjured" on the incident report, but she was also taken to the hosptial as a precaution. No immediate updates on her condition.

Justin Bieber was among many using the hashtag getwellsean on Twitter, posting a message for Kingston on Monday that said, "I will continue to support and pray for my friend."
