Weeks before she welcomed her little one, Chabert couldn't be more ready to give birth.

"#currentmood," she captioned a hilarious meme in late August. "Thanks for this @jonathanbluth Made me laugh so hard."

Yes I'm uncomfortable and counting the days of this final month of pregnancy but I will miss our afternoon naps. Kitty loves to nap on the baby bump-I won't let her put her head on my belly anymore though because I'm worried it's too heavy-she's a chubby little chihuahua ���� #kitty #chihuahua #bigsister

So I definitely haven't been being filmed from any side angles in this movie ���� Thank you to @seraphinematernity for this dress which worked its magic to help hide the baby belly from the front! #hidethebabybelly #maternity #whenyourcharacterisnotpregnantbutyouareveryveryverypregnant
