In 2009, the couple's 16-year-old son, Jett, died unexpectedly after he hit his head in a bathtub during a seizure while the family was on vacation in the Bahamas. Five years later, Preston gave birth to Ben.
During an interview with Good Morning America on Monday, Travolta shared that his youngest child has helped the family heal following Jett's death.
“We certainly have bonded together,” the 62-year-old Gotti actor said. “And certainly, having little Ben has been a beautiful kind of glue for us to rebond after tremendous loss.”
After winning an Emmy for producing The People v. O.J. Simpson: American Crime Story earlier this month, Travolta thanked Jett when he spoke to ET. "The biggest thanks has to go to [show creator] Ryan Murphy, because he made this all possible," Travolta said. "And my family: Kelly, Ella, Ben and then my little Jetty, I love you all so much."
