I really don't understand the concept of a fake accent under these circumstances.
Madonna when married to Guy Ritchie suddenly speaking English with a British accent instead of an American at age 42 is fake.
Someone learning English from a teacher, parent or environment with an American or British accent - developing an American or British accent is not fake.
When I was taught French I was not taught how to speak it with an American accent. That I did anyway didn't make me more genuine than someone who had mastered the accent.
Your first language has a huge impact on your English accent. Most of BW starkids first language is Hindi so when they are trying to speak English with an American accent it's 99% fake unless they live in America. They can't copy British accent because it is really difficult even Shraddha Kapoor in an interview said she tried to copy American accent in the beginning but failed pretty badly and what's wrong with Indian accent? Kunal Nayyar, SRK, Hrithik all have Indian accent yet they are good.
