Housemate Exchange

On December 17, 2009, the Spanish Big Brother Gran Hermano 11 revealed a housemate exchange with another country will take place. It was revealed the exchange will be with Grande Fratello; the decision most likely comes as the television station that programs the Spanish and Italian versions of Big Brother are owned by the same company, Mediaset. On December 29, during the spin-off show of Gran Hermano: El Debate, it was shown to the Gran Hermano housemates that the Italian housemates taking part of the exchange will be Carmela and Massimo; they arrived at the Gran Hermano house on January 3, 2010; that same night it was announced that the Gran Hermano housemates involved in the exchange are Saray and Gerardo. The Gran Hermano housemates arrived the next day in the Grande Fratello house (Day 71) and stayed till January 9 (Day 77). Carmela and Massimo left the Gran Hermano house early January 10 and returned to the Grande Fratello house on January 11 (Day 78) during the eviction show.
