New Delhi, March 21: Celebrity memoirs and biographies, despite the terrific attraction they have for readers, have come to be quite controversial in recent times. It was not very long ago that actor wazuddin Siddiqui was compelled to withdraw his memoir “An Ordiry Life” and it seems yesterday once more with Bollywood star Sanjay Dutt “upset” over his “uuthorised” biography by Yasser Usman. For well over past one month, the publisher, Juggerut Books had been approaching media outlets with their “hottest book in March”, sharing the electronic copy or the pdf of the book with concerned reporters and setting an embargo till March 20 for extracts from the book to be published. Even as a couple of extracts appeared a day or two before the agreed embargo, it was only on Tuesday evening (March 20) that Dutt took to twitter and conveyed that he was “upset” with this “uuthorised” biography by Yasser Usman.
