Kingston, 21, was driving the personal watercraft with a female passenger on board when the accident occurred, said Officer Jorge Pino, a spokesman for the Florida Fish and Wildlife Conservation Commission.

About 6 p.m., the hip-hop and reggae singer slammed into the Palm Island Bridge, which connects the MacArthur Causeway to Palm and Hibiscus islands. Both he and the passenger were thrown into the water, Pino said.

A passing boater saw the accident and took the two on board his vessel.

Miami-Beach Fire Rescue took Kingston to the hospital. His condition was not immediately known.

Scores of nationally known hip-hop artists converged on Miami Beach this weekend for Urban Beach Week.

Kingston’s first single, Beautiful Girls, topped the Billboard charts for three weeks in 2007. He recently toured with pop superstar Justin Bieber.
