The hip-hop star and a female passenger were rushed to hospital after colliding with a bridge at 6pm local Florida time.
'South beach... #nicee... bout to get fresh and cause that movie!!...' Sean told his 1.6 million followers on Twitter 18 hours ago, before he took to the water.
'The Miami Fire Dept. responded to the scene and both Kingston and his female passenger were transported to nearby Jackson Memorial Hospital,' reports TMZ.com.
'We're told Kingston's injuries are so severe, he is being treated in the trauma ward.'
The 21-year-old's rep confirms: 'Sean Kingston was in an accident today. No further details are available at the moment. He and his family thank everyone for the well-wishes.'
