She kept it to only one curse word, which is impressive for Joan!
"He's f–king adorable."
That he is, Joan.
Joan's own daughter also had some encouraging words about the baby and the new mommy.

"Oh, he's precious. Giuliana's going to be a great mom. I can't wait to see her at games. I can't wait to see her as like the crazy soccer mom. She always makes fun of me, and I know she is going to be absolutely nuts."
We wouldn't go that far, but we're sure she'll be plenty excited!
Nuts? That isn't nice, ha!
