Montoya and Anita's relationship came under strain early in the series, when single guy Manuel set his sights on Anita and single girl Gabriela took a shine to Montoya.
Montoya and Anita, 26, started going out a year before they entered La Isla de Las Tentaciones - the Spanish version of US show Temptation Island.
But who is TV star José Carlos Montoya, and what is going on between him, his girlfriend Anita Williams, and their single co-star Manuel?.
Things took a turn for the worse when Anita was shown footage of Montoya receiving a lap dance from Gabriela, and decided to pursue her connection with Manuel as revenge.
Spanish reality series La Isla de las Tentaciones has gone viral thanks to a clip of a man breaking down as he watches his girlfriend have sex with someone else.
