Why Shweta Tiwari became Ridheema Tiwari

Her mother Madhuri is a diehard fan of Amitabh Bacchan the reason she kept her children's name as Abhishek and Shweta. Even Ridheema is a huge fan of Amitabh Bachchan. Though she still uses Shweta as her name in records including the contracts and bank, it's only for the screen that she becomes Ridheema Tiwari only.
