John Travolta and Kelly Preston are planning to extend their family - before it's too late. The couple is currently working on new movie Old Dogs, which they both star in.

When that's wrapped the pair will start trying for a sibling for son Jett, 15, and eight year old daughter Ella. Travolta, 53, says, "Once we finish our new movie, we're going to get cracking. Kelly is 44 now. The window for us to have a child, at least naturally, is closing."
