We are not sure as to how to react to the sexiest installment of the Hate Story franchise. Directed by Vishal Pandya this movie stars Katrina lookalike, Zarine Khan, Sharman Joshi, Daisy Shah and Bipasha Basu's rumored boyfriend, Karan Singh Grover. We are amazed big time with the total number of sex scenes released in the trailer. Take a look at it and well, err, gear up for the  third installment of the erotic thriller .
