For about the 700th time in the last year, John Travolta is telling the world he wants another baby with wife Kelly Preston. Because that’ll make the gay rumors go away for good. Just ask Tom Cruise.

“I was told by Kelly that at the end of the summer we’re going to try.”

Adds Kelly:

“[We'll try] after we finish the movie we’re doing together, Old Dogs, with Robin Williams and our daughter Ella. So after that!”

Dude, she’s 44 years old. If they were truly serious about this, they’d be “trying” now, not later. Maybe JT needs to psych himself up for that project, though. Masseusses of L.A.: watch out!

Besides the above mentioned Ella, 7–who they ALWAYS talk about and take everywhere–the couple has a 14-year-old son, Jett…who they RARELY discuss and is hidden away most of the time. There’s been rumblings for years the boy is autistic, though Kelly, in all her Scientology self-righteousness, insists he suffers from Kawasaki’s Syndrome, though that’s not a chronic condition.

Ten bucks says this phantom third child never happens.
