Congrats are in order!

Zoe Saldana announced on Instagram that she and husband Marco Perego have welcomed a new baby boy, and she must have quietly used a surrogate, because she was never seen with a baby bump!

"Marco and I are elated to share the news of the birth of our son Zen. We couldn’t feel more blessed with the new addition to our family. #threeboys… oh boy!” she captioned the snapshot.

The couple are also parents to twin sons Cy and Bowie, 2.

That's a full house!
