Bibi is the only character who does not wear any plush clothes.
The story of how Ludovico and Federica met and married changes each season.
In every episode, Consuelo Duval wears clothes that show her bare belly.
A fourth season is still in talks, but it will be difficult since Consuelo Duval's departure from Televisa, the show's production company.
The crew has said that Regina Blandon (Bibi) was the most difficult actor to work with as she never remembered her lines and always laughed during her scenes.
Edgar Vivar: as The Doctor in the Episode "Federica is Sick" from Season 3. Vivar played Señor Barriga in "El Chavo del 8" (1971). He is a real surgeon; he studied medicine back in the 1960s.
