Answer 1

kapu. she hails from rajamundry her original name is suhasini rajkumar naidu.

A correction, Sneha is from Tamil Nadu, from a place called Panruti, though it says she is from a Naidu family, it does not say whether she is a kamma naidu or Bailija Naidu. Pls check her Wiki here

her actual name is Sneha Rajaram Naidu.
