Katrina to do an item number again

'Aaya Re Aaya Bodyguard'....that's the item song which Katrina would be joyously gyrating to in Bodyguard. Even as Katrina gears up for the challenge of outdoing her 'Sheila Ki Jawaani' number she has a bigger challenge to meet up to.

Salman Khan aka the King Of All He Surveys, will also be part of the song. Apparently, he reasoned that since the song is about his character, Bodyguard ka hona to haq banta hai, boss. Now Ganesh Acharya has been asked to incorporate Salman into Katrina's elaborate item number.

Apparently, Salman wants the number structured like 'Sheila Ki Jawaani' where Akshay Kumar joins Katrina. That is easier said than done.

Says a source, "Salman likes to do his own thing in the dance numbers. Everyone knows in 'Munni Badnaam' he didn't follow Farah Khan's instructions. Katrina will be rigorously rehearsing her steps for 'Aaya Re Aaya Bodyguard'. She wants it to be as perfect as 'Sheila Ki Jawaani'. Salman's improvisations are bound to distract her. But the there is not much she can do about it. Because as Salman pointed out the song is about him, so he has to be part of it."

Bodyguard producer Atul Agnihotri confirms that Salman would be part of Katrina's item number.
