BBB never had Portuguese housemate
Only a French housemate in BBB1 and a Argentinian housemate in BBB4
Well, I think Portugal is ever more interested in the other countries, than the other countries in Portugal. That's why I say that we like when someone who isn't portuguese want to learn about the country, it demonstrate that countries are also interested in us, not only us interested in other countries.
I think an Argentinian housemate is pretty commum there, because Brazil and Argentina are neighbours. I remember now that Daniela S from SS2 is original from Spain, and she arrived to the 3rd Place!
