Actress who is playing Rishitaās role in the Original, Meena is the character name ( actress name is Hema) got pregnant in real life and makers wrote the pregnancy track for her, thatās how Meena ended up having a child before Dhanam š - So method acting has been used in the OG š
That has been followed by all the other versions including this one but at the last minute Leadben here wanted a baccha before Rishita, so the makers have brought in this readymade baccha trackš
As for leadben being pregnant in real life, I got to see it to beleve it, āshow me the baby bumpā after 4-5 months š
