So, what did Rani Mukherjee do on her birthday that was on March 21? If your guess is she had a bash like most Bollywood celebs, you are light-years away from the truth. Here's one celebrity who is thoroughly and genuinely different. Rani spent this day with the students of The Helen Keller Institute for the Blind and Deaf.

The actress had befriended the members of this institute, when she was doing her role of a blind and deaf girl in the highly acclaimed movie 'Black'. She visited The Helen Keller Institute to know more about these children of a lesser god.

For all the awards that Rani won for the best actress for the film Black, she expressed her gratitude to these students, without whom she claims she would not have been able to deliver such an exceptional performance.

We wish Rani Mukherjee a very Happy Birthday; hope she has a great year ahead. - SAMPURN
