I know this is a mean thing to say but may be it's because of her age too but I really found her reactions over the top to another level.
Actually I watched the live feed thanks to ShahZur and even her mother was rather taken aback by the excessively loud crying and in the livefeed it started way before her mother even came, in fact started as soon as BB announced it was Nikki's turn and she told her mom sab log mujhe badtameez bolte hain and her mother said no no. They cut that part.
How much she was bawling in the livefeed it was crazy!
