America is feeling the Bollywood heat these days. Karan Johar is in the country with along with Abhishek Bachchan, John Abraham and Priyanka Chopra for Tarun Mansukhani's directorial Dostana but to everyone's amazement the stars are on a virtual holiday.

The reason... Tarun is single-mindedly shooting an opulent item number with Shilpa Shetty for almost a week, leaving the rest of the cast with nothing to do.

According to an insider, the song is peppy and will be one of the major highlights of the film. Shilpa will be seen in a totally new rock-chick avatar. Shilpa shows off her curves in the song.

The song will reportedly feature at the beginning of the film. Shilpa has been shooting the number on Miami's scenic beaches. But the highlight of the number is a sequence in which Shilpa rides pillion on a bike with a group of bikers.

Reports say Mansukhani hired a real gang of bikers for the song. Shilpa apparently had whale of a time shooting with the bikers.

At the end of the number, Shilpa reportedly turns into a narrator and introduces the movie's two male leads – Abhishek Bachchan and John Abraham.
