Actress Nargis Fakhri is said to be doing the best that she can for her debut item number in "Phata Poster Nikla Hero".

Nargis will shake a leg with Shahid Kapoor for the number, composed by Pritam, and choreographed by Bosco-Caeser.

Details of the number are being closely guarded, but one hears that the "Rock On!!" actress will be presented in an all-new avatar. A popular stylist is said to have been roped in for the same.

Directed by Rajkumar Santoshi, "Phata Poster Nikla Hero" stars Ileana D'Cruz with Shahid.
