Her proximity to Amitabh Bachchan seems to have made a perfectionist of newcomer Jiah Khan. The actress, we are told, has just signed a film requires het to completely change her look and ‘bodytype’. In fact, she’s taking her new roles so seriously that she’ll soon be off to London for 10 days to undergo a whole excercise which will have her looking completely different from what she did in Nishabd. Whew! If this is the younglady’s passion for work in her initial films, her producers certainly have a winner on their hands!
