London, January 8 : John Travolta will bid his late son, Jett, a final goodbye in a private Scientology memorial service.

The actor's 16-year-old son, who had Kawasaki Syndrome, a rare condition that can lead to heart disease, died from a seizure on January 2 during a family holiday in the Bahamas.

He was cremated on January 5.

Travolta and his wife Kelly Preston are said to have invited close friends, including Scientology practising Tom Cruise, Oprah Winfrey and Kirstie Alley, to the service on their Florida property.

The 54-year-old devastated dad was reportedly struggling to deal with the tragedy, according to a source.

"Forget that John is a big Hollywood star. He is just a grieving father who is struggling to cope with the loss of his beloved son," the Sun quoted a family friend as saying.

"He isn't ready to face the public, and won't be for some time. His grief is raw and it is going to take him and Kelly a long time to recover from this," the friend added. (ANI)
