Actress Priyanka Chopra says she is unnerved about her role in Vishal Bharadwaj's "Saat Khoon Maaf", in which she will have seven husbands.

"Preparation for Vishal sir's film (is) in full swing...One of the toughest characters of my life...so scared...Don't know how I'll pull it off," Priyanka posted on her Twitter page.

While Naseeruddin Shah plays her oldest spouse in the movie, Neil Nitin Mukesh has just been signed to play the youngest.

Priyanka has previously worked with Bharadwaj in "Kaminey" and her performance was highly appreciated.
