Star report that the couple are thinking of adopting a child a few years younger than their nine-year-old daughter Ella, after friends suggested it could be a good way to help the grieving family move on.
“Ella said it would make Jett happy to see Mom and Dad smiling again," said their source.
"They really believe another child will benefit the whole family, and it will be a beautiful tribute to Jett.”
John and Kelly are devoted Scientologists and are said to be considering the same adoption agency that Tom Cruise and Nicole Kidman went to when adopting kids Isabella and Connor.
“The church has access to adoptable Scientology children,” the source said.
“Members encouraged John and Kelly, telling them that bringing another child into their home is the right thing to do.
The Travoltas are still "shell-shocked" after 16-year-old Jett died fllowing a seizure.
“Their grief is beyond words," said the source.
"John feels like his heart has been ripped out. He shuts himself in a room for hours, while Kelly grieves alone.”
