It was back to school for Teresa Giudice's girls this week… all four of them! The Real Housewives of New Jersey mama took to Twitter to share some pics of the little ladies getting ready to board the bus. As it turns out, only one of the four was nervous for her first day, and it's definitely not who you would expect!

Tre posted a pic of her three oldest, writing, "First day of school Gia and Gabriella were very excited Milania was a little nervous. Love them so much."

That's right: Super outgoing and outspoken Milania was the only Giudice kid with butterflies in her stomach that morning. We would never have guessed in a million years that Milania would be nervous about anything.

Even the baby of the family was feeling confident and raring to go.

Moments after sharing the first pic, Teresa added a photo of her youngest, gushing, "Audriana's first day of school she was so excited love her so much."

We hope the girls have a great year!
