John Travolta's son, 16-year-old
Jett,
died today, Friday.
Jett died while the family was on vacation in the Bahamas.
While circumstances surrounding the death are unknown, it can be surmised that it has something to do with Kawasaki disease, from which Jett reportedly suffered.
The Travolta's never publicly confirmed or discussed this.
Not much is understood about Kawasaki disease, which is a condition that affects many parts of the body. It affects mostly boys under the age of 5.
