Katrina won't just be doing an ordinary cameo in Bodyguard. Instead, Kaif is all set to sizzle in a grand item number that will play during the opening credits of the film.

It is said that Salman was so impressed with success of 'Sheila Ki Jawaani', that he requested Katrina to be a part of the opening-credits of the film. The item song in question for the opening credits will be composed by Himesh Reshammiya and Ganesh Acharya will choreograph the song.

If that wasn't enough, we also hear that the item number will be on the lines of James Bond's opening credits.

The song will be shot on July 26.
