John Travolta shares touching birthday tribute to his son Jett who died 13 years ago

Travolta posted a short but heartfelt message on Instagram saying: "My dearest Jetty, I miss you more than words can say. I think about you everyday. Happy Birthday. Love, your Dad."

Jett died in 2009 in the Bahamas after hitting his head on a bath while having a seizure. He was autistic, suffered from seizures and had a rare condition called Kawasaki Syndrome, where the wall of the arteries become inflamed. 

In 2014 Travolta told US Weekly he didn't know if he would make it through the grief of losing his son. 

John Travolta on his Emmy nomination: 'I'm still in the game'

The actor recently earned his first Emmy nomination for his revelatory performance as Robert Shapiro in "The People v. O.J. Simpson: American Crime Story," but Travolta didn't see it coming.

"I did not assume at all [that I would be nominated] by the way, because I've been around too long," Travolta told CNN in an interview on Wednesday. "I've been acknowledged over the years for various performances, but the big acknowledgements were "Saturday Night Fever," "Pulp Fiction" and this."
