John Travolta and Kelly PrestonJohn Travolta and Kelly Preston have a noisey household these days, and they have their new baby boy to thank for it.

The couple welcomed their bundle of joy, Benjamin Hunter Kaleo Travolta, last November, and has Travolta warming up his singing voice "all the time."

"I make up songs," Travolta told Us Weekly. "I was changing him the other day, and I wanted to entertain him so he didn't get upset, so I made something up."

Preston, who graced the cover of Hello! magazine earlier this month with Travolta and baby Ben, revealed the new addition to the family looks "identical" to his dad.
