ONE TIME DANCER AND HOLLYWOOD STAR JOHN TRAVOLTA'S SON DEAD AT 16!

Rand Memorial Hospital in the Bahamas tells TMZ the son of John Travolta died today.

We're told 16-year-old Jett was vacationing with Travolta and wife Kelly Preston.

There have been reports that Jett was autistic, though Travolta has denied it, saying he suffers from Kawasaki Syndrome, a condition which often leads to heart disease.

UPDATE: 4:00 PM ET -- Travolta's attorney Michael Ossi says 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 scene.

Rand Memorial Hospital is in Freeport, Grand Bahama.

Jett was born on April 13, 1992. He was named for his dad's love of flying.

Jett has one sibling, younger sister Ella Blue.

Here are some Jett Travolta photos with his parents when he was a baby and younger child.
