Actress Sonakshi Sinha, the girl who sizzled with her onscreen debut in films through Salman Khan's 'Dabangg' is all set to play the role of Kamal Haasan's wife in his upcoming bilingual movie to be directed by Selvaraghavan. Doesn't she feel quite doubtful over her onscreen chemistry with Kamal Haasan, who is 33 years old than him. 'Definitely not… In real life biological age doesn't mean anything between a couple and so it is with the onscreen as well. Since I am of young age, it doesn't mean I can pair only with the teen-actors. I have been working with Salman Khan and Akshay Kumar, who are very much senior to me and our onscreen chemistry is best to watch out for. Similarly my chemistry with Kamal Haasan will be great and we are hoping for the best.'
