JOHNJETT.jpg John Travolta's 16 year-old son Jett died today while the family was on vacation in the Bahamas. According to TMZ, Jett suffered a seizure at his family's vacation home at the Old Bahama Bay Hotel on Grand Bahama Island. Attempts to revive him were unsuccessful, and he died on the scene. New reports state Jett hit his head on a bathtub in the family's quarters at the Old Bahama Bay Hotel during the seizure, causing a fatal injury.

Circumstances of his death are unknown, but Rand Memorial Hospital confirmed the fatality.

It was rumored that Jett was autistic, but John has denied those reports and instead said that his son suffered from Kawasaki Syndrome, a condition which often leads to heart disease.

We last saw the father and son together in Paris just a few weeks ago ...
