Who helped Alia Bhatt prepare for 2 States?

Alia Bhatt plays a South Indian girl in the upcoming film 2 States. Though the Student Of The Year actor comes from filmi family, the two film old Alia definitely needs some preparation to play different roles. So who has been helping her for 2 States?

Alia Bhatt is playing a Tam-Brahm in the film and she needed help with her accent for her role in 2 States. A little birdie tells us that South actor Revathi helped Alia to perfect her Tamil accent. Revathi plays Alia’s mother in the film and looks like she took her role a tad too seriously, no? The pretty lady turned a mother for Alia in real-life too by giving her some language lessons.

The film is based on a Chetan Bhagat novel of the same name.
