Chi balla con me, balla con due donne

"Who dances with me dances with two women" is what that means. She hadn't even mentioned the fact that she was pregnant for several dances, so we were starting to wonder if she was just playing a joke on us, and wearing a fake belly. She was definitely amazing even for an unpregnant (word?) woman. But finally when these two had finished showing us different dances and begun to dance with the students, she said this, and I thought it was one of the most romantic ways she could have referred to her pregnancy, and told us the gender of the baby. Hurrah for her!
