Creators Florencia Bertotti and Guido Kaczka were married at the time of production. She is now married to Federico Amador (Tomás), whom she met during filming.
Cris Morena thought this series was too similar to Floricienta (2004) and sued creators Florencia Bertotti and Guido Kaczka. Kaczka has starred in Morena's famed productions Chiquititas (1995) and Rincón de luz (2003). She won the case and "Nini" ended up being canceled.
Cris Morena said of this series, "Sometimes people make mistakes, and Florencia Bertotti made one. You cannot copy something you've just finished". In her defense, Bertotti stated, "I made no mistakes. I was a tomboy on 15 out of 30 scenes I shot. I had never done that before. The real problem was that my show competed with the ones she creates."
