Priyanka chopra is learning the south American danceform “tango” for her forthcoming film ” saat khoon maaf” which is directed by Vishal Bhardwaj. Her character in film is a master of tango and she isn’t going to do the tango dance with any of the lead actors or her husbands, she will do it with a supporting actor. Guess we have to wait to look Priyanka performing tango.
