Vidya Balan who hasn’t signed a Hindi film post Tumhari Sulu, has begun shooting for the NTR biopic. The actress, who flew to Hyderabad last week, returned to Mumbai two days back. Since then, she has been taking harmonium lessons. A source close to the actress says, “Vidya has got a personal trainer and is taking harmonium classes. Although she knows a bit of it already, she wanted to fine tune her skill. She is devoting two hours regularly for the same.”
