Carlota Prado was escorted to a room, where she was shown footage that allegedly showed Jose Maria Lopez Perez sexually assaulting her following an on-set party that involved alcohol.
Prado asked for the footage to be shut off, but was told by a narrator there was more to watch.
Endemol Shine, which owns the production company that runs Gran Hermano, has admitted it regrets the way the situation was handled.
Prado was later given time with a therapist and Perez was removed from the house.
