"Being a victim myself, I relate to these incidents so often be it on television or on my social media accounts and it appalls me the kind of language one uses. I was keen to express this and understand the psyche on the comments made by them," she added.The actress will be accompanied by strong women personalities for the show.The TV show brings celebrities and their trolls face-to-face. Zareen has already started shooting for the show, which is aired on MTV. "On my first episode as a host, I will be joined by a woman who's known for being forthright and strong headed - Mandira Bedi. Trust me, it will definitely be an exciting episode for the viewers who will witness women taking charge and with this, I hope it encourages women and one and all to step up because ignorance is not always bliss," she added.
