The speculation over the father of Bengali actress and Trinamool Congress MP Nusrat Jahan's newborn son Yishaan J. Dasgupta has been put to rest by the infant's birth certificate on the website of the Kolkata Municipal Corporation. Yishaan was born on August 26.

Nusrat has been dating Bengali actor Yash Dasgupta after her much-publicised estrangement with her husband Nikhil Jain. Speaking to the media recently, she referred to the talk about the father of her newborn child, and said: "I think that's a vague question to ask and put a black spot on somebody's character as a woman. The father knows who the father is and we are having a great parenthood moment together. Myself and Yash, we are having a good time."
