Rahul and Javed shake legs with Saif's ex

Saif Ali Khan's ex-girlfriend Rozzaa Catalano is finally making her big screen debut and she has Rahul Bose and Javed Jaffrey for company.

She is being seen in an item number 'Jaane Kyun Jaaneman' which has been shot for the film Shaurya. Though this Samar Khan directed film is centered on an Army Court Martial, it also has relief elements in the form of a couple of item numbers (though going with the narrative of the film), one of which is 'Jaane Kyun Jaaneman'.

The song shows numerous youngsters with their spouses/girlfriends partying in a nightclub with blazing lights, rocking beats and a DJ at work. In addition, there is Rozzaa for company who gets grooving on the dance floor. In the process she also involves Javed Jaffrey and Rahul Bose who after initial reluctance join in and drop their inhibitions. While Jaffrey gets into a 'boogie-woogie' mode, though just for a short while, Rahul Bose is fun to watch as he gets 'bindaas' with his awkward movements, going with the demand of the character.

A club track with all around Western mode and styling, 'Jaane Kyun Jaaneman' is sung by Adnan Sami (who also composes the track) and Sunidhi Chauhan. The two have also sung another item number 'Dar Dar Ke Mar Mar Ke' which is yet to be unveiled.
