Bollywood's own Sunjubaba - Sanjay Dutt is playing off-screen mamu to his little niece, sister Priya's daughter. He's been spending a lot of time at home playing with her, and most of all teaching her. He finds special joy in teaching her small words and hearing her do all the baby talk. Even Priya vouches that her little girl is obsessed with her uncle. Hope Sanju is not teaching her in such a tapori twang!
