Sean Kingston Cassandra SanchezSean Kingston's passenger, Cassandra Sanchez, is speaking out about the pair's reckless jet ski romp turned serious hospital stay. Sanchez, who is Kingston's longtime friend, recalls begging the singer to slow down before the pair crashed into the Palm Island bridge in Miami.

"Both jet skis pulled out of the dock at the same time and we were going so fast we just blasted past them," Sanchez told TMZ. "When we turned a corner and crashed ... they were so far behind us they didn't even see us crash."

As the pair were approaching the bridge Sanchez recalls they were traveling "really fast."
