And it is evident that former Miss India World Sarah Jane Dias is playing heroine besides power star. No wonder the actress is having goosebumps to work with Pawan Kalyan and in the process , she's addressing Pawan as “Sir”. However,  Pawan asked her to stop calling him as Sir. Sarah tells us more on this - “I enjoyed working with Pawan Kalyan. Initially, I addressed him as ‘Sir' but, he asked me to stop it. Even Today, we laugh about it,” said the former beauty pageant, whose career largely depends on the outcome of her debut movie.
