Kamasutra 3D actress Saira Khan passed away after being suffered a cardiac arrest, Indiatoday.in reports. Saira made the headlines after she replaced Sherlyn Chopra in the controversial 2013 film. Saira belonged to a conservative Muslim family, and it was difficult for her to make a debut with an erotic movie like Kamasutra 3D. The film was first screened at the 2013 Cannes Film Festival. It is an Indian English language erotic drama film. Meanwhile, the director of the movie, Rupesh Paul said ‘I found out about the news and was shocked.’ He added, ‘Later to see nobody and nowhere it was even reported was even more shocking. She deserved to be recognised for her performance and to remain unknown even after the brilliance she had is even more hurtful. It’s a mourning time for us and I hope she rests in peace.’ While the actress went unnoticed after this movie, it is shocking to know her sudden demise.
