Nargis Fakhri, the 'Rockstar' debutante became a rapper to accept Duggu aka Hrithik Roshan`s 'Bang Bang' challenge. She was seen in a black costume wearing a hat and was rapping like a professional....

Quite impressed with her attempt, a thrilled Hrithik tweeted thus, "Woman!! I still can't get over your rap! I hope u know how amazing u r. True feminine power! Love u n inspired by u! @NargisFakhri."

Nargis isn`t the only Bollywood actor to have accepted Hrithik`s challenge. Priyanka Chopra, Shah Rukh Khan, Sonam Kapoor, Farhan Akhtar. The list is long! But this is truly a unique marketing strategy that has worked for the film.

Directed by Siddharth Anand and also starring Katrina Kaif, 'Bang Bang' releases on 2nd Oct.
