Vanessa Lachey is showing off her fast growing baby bump and her proud husband and dad-to-be Nick Lachey.

The pair is expecting a baby boy who is due in a little over a month on September 6. The happy mom tweeted this adorable photo (with her self-reported disappearing belly button) with the caption,  “My Happiness… My Family! Ahhh, My Boys! (Wookie included) ”

“You see him in sonograms and you feel him move — you just want to meet him!” Nick said excitedly during a recent press tour. “Hurry up and get out of there!”

Congratulations to the expectant parents!
