^Actually, for sometime now, I have suspected that Tatiana is well versed in Portuguese because of her Brazilian mother, and maybe Andrea picked up some of that from her. Also, the Casiraghis have spent a lot of summer holidays at Charlotte's godmother's in Portugual, and then there are the recent trips to Brazil, so..... I don't know. I mean, I'm sure Albina is French all the way, and Tatiana probably speaks French and English above anything, but still, it wouldn't surprise me if they all knew a little Portuguese. I think Andrea is more likely to speak English and/or French with Tatiana, and they might speak some Portuguese in Brazil, and maybe a little Spanish when they go to Ibiza/Formentera. And Charlotte's boyfriend is, like Tatiana, half-Brazilian. Remember that he spent much time there as a kid. No doubt Charlotte and Alex are most comfortable with English, together, but I'm guessing Alex is at least partially fluent in Portuguese.
