She is the epitome of 'V'ulnerability, 'I'ndian-ness, 'D'earness, 'Y'outh, and 'A'ttitude. For those in the know, will surely know whom we are referring to. But for the uninitiated, she is the one and only Vidya Balan, who celebrates her 31st birthday on Friday. Not many know that this Gen-Next's Dream Girl started her affair with the camera with the Malyalam movie 'Chakram', a film in which she was paired opposite the southern superstar Mohanlal. And as far as the ad world is concerned, it was the Surf Excel commercial that paved the way for the 'Excel-lent' actress into the silver screen. And the resultant of this was the Pradeep Sarkar directed Parineeta, a film that gave Bollywood its very own Superstar in Vidya Balan. Vidya repeated the success of Parineeta with films like Lage Raho Munna Bhai, Guru, Salaam-e-Ishq: A Tribute To Love, Bhool Bhulaiyaa, Heyy Babyy and the more recent smash hit Paa. Vidya has everything that is required of a Diva. In other words, it becomes totally needless, to say that Vidya is definitely a Diva in the making.
