Friend: Travoltas' faith, family 'solid'

OCALA, Fla., April 8 (UPI) -- U.S. film stars John Travolta and Kelly Preston are keeping a low public profile, but spending time with family and friends following the death of their son.

Jett Travolta died in January of a seizure disorder. He would have been 17 on April 13.

A family friend told People.com: "They aren't secluding themselves or paralyzed. ... (Seeing them) was like old times. Nothing awkward and no topics to dance around. There were smiles."

"John is a strong man, but we want to leave him in peace," Olivia Newton-John, Travolta's "Grease" co-star and another longtime friend, told the magazine. "To lose a loved one -- it's the worst time in anyone's life."

"They're relying on their (Scientology) faith to get them through this," a source close to the family said. "Their faith is solid, and their family is solid."
