John Travolta just announced on his website that his fam is growing -- but didn't flat out say wife Kelly Preston is pregnant.
The family writes: "It's impossible to keep a secret... especially one as wonderful as this. We want to be the first to share this great news with everyone that we are expecting a new addition to our family."
The note is signed by John, Kelly, and their ten-year-old daughter Ella.
Whatever the addition, congrats to the Travoltas!
UPDATE: Kelly's rep confirmed she's pregnant.
