John Travolta and Kelly Preston's son, Jett, has died while on holiday with the family in the Bahamas.
According to a police statement, Jett hit his head on a bathtub on Friday morning.
The family's lawyer, Michael Ossi, told Reuters that Jett, who was 16, had suffered from a seizure at the family's holiday home at the Old Bahama Bay Resort on Grand Bahama Island.
A caretaker found the teenager unconscious in the bathroom at around 10am and attempts were made to revive him but he was declared dead at Rand Memorial Hospital.
An autopsy is being undertaken to determine the exact cause of death.
Back in 2003, Kelly revealed that when Jett was two, he became ill and was diagnosed with Kawasaki disease. The condition can cause inflammation of the arteries but is usually treatable - although it can cause lasting heart damage in rare cases.
John and Kelly also have an eight-year-old daughter, Ella Bleu.
