Sean Kingston on the mend

MIAMI, June 3 (UPI) -- Sean Kingston remains hospitalized in Miami after a jet ski crash, but he is showing signs of improvement, sources close to the singer told TMZ.

The celebrity news Web site said Friday Kingston still has a breathing tube in his mouth so he can't talk, but he is awake, alert and communicating through nods and sign language.

Doctors expect him to stay in the hospital for a few more weeks, TMZ said.

The 21-year-old recording artist and a female passenger were injured Sunday when their watercraft struck the Palm Island Bridge. Another person rescued Kingston and his companion from the water.
