At a press meet here, their mother, Razia was asked if she would get Gauhar and Kushal married.
She said: "Gauhar is a very intelligent girl. If she wants, then we will definitely take things forward."
However, Nigaar said one needs to wait a bit to watch what the future holds.
"Let's not hatch eggs before they are laid. It's something very sweet and we saw two people respect and support each other. Let's not think about what will happen in the future. Let's be happy about today," Nigaar said here.
"Even you (media) can't guarantee what will happen in the future, then how can Gauhar. If they both stay with each other, then let's see," she added.
Nigaar also took her sister's side by saying that she wouldn't make statements just to attract good ratings for a show.
"Gauhar is not a girl who will say something only for ratings. If she has said 'I love you' to Kushal on national television, then she definitely must have felt it at that moment and is why she said it," Nigaar said.
Gauhar won the seventh season of the show, and walked away with Rs.50 lakh at the grand finale held Dec 28.
