EXCLUSIVE: Grease Director Happy John Travolta And Kelly Preston Have "Some Joy In Their Lives"

Congrats is the word the director of Grease has for John Travolta and his pregnant wife Kelly Preston.

Randal Kleiser spoke to RadarOnline.com exclusively at a screening of the new sing-a-long version of his film Grease.

"That's terrific," said the acclaimed director when responding to 47-year-old Kelly being pregnant. "Some joy in their lives after all the hard times they've gone through. They're both wonderful people."

John and Kelly's 16-year-old son Jett died in January 2009 of a seizure during a family vacation.

Randal keeps in touch with the John; they saw each other at a Christmas party last year.

In fact, Randal found out 30 years ago that the couple was destined for each other.

"I actually interviewed Kelly for the Blue Lagoon. She's one of the  people we considered for that but she seemed too wise to me," he said. "At  the time I interviewed her, she said 'Grease is my favorite movie and  some day I want to marry John Travolta',"
