John Travolta and his wife Kelly Preston have issued a heartfelt statement about the tragic death of their son.

Jett, 16, was found unconscious in the bathroom of their suite at the Old Bahama Bay resort, Grand Bahama, after apparently suffering a seizure and hitting his head.

The teenager was rushed to hospital on Friday morning but pronounced dead on arrival. A post-mortem is expected to take place today.

The statement - from John, wife Kelly Preston and their eight-year-old daughter, Ella - posted on Kelly's official website reads:

We would like to extend our deepest and most heartfelt thanks to everyone who has sent their love and condolences.
Jett was the most wonderful son that two parents could ever ask for and lit up the lives of everyone he encountered. We are heartbroken that our time with him was so brief. We will cherish the time we had with him for the rest of our lives. We have received many messages of condolence from around the world and we want to thank everyone for their prayers and support. It has meant so much to us. It is a beautiful reminder of the inherent goodness in the human spirit that gives us ahope for a brighter future.

 With love,
