Imran Khan plays the lead role in "Delhi Belly" and also features in the just-released promotional song "Bhag D K Bose", but for the item number that is to be added to the adult comedy, he wants Katrina Kaif.

The video, launched Wednesday, also features Vir Das and Kunal Roy Kapoor, who play important roles in the film, directed by well-know ad-filmmaker Abhinay Deo and produced by Imran's uncle Aamir Khan.

Following the trend, Aamir has decided to add an item number in the film, but he hasn't decided on whom it will be picturised.

When reporters asked Imran who his choice would be, he promptly replied: "My vote is for Katrina Kaif. I have told Aamir mamu that he should consider her for the item number."

What's so special about Katrina? Imran smiled and said: "For her jawani."

Imran has made it clear that "Bhag D K Bose" is not to get one up on Ranbir Kapoor, whose "Rockstar" would release just after "Delhi Belly", which is releasing July 1.

"There was an article today (Tuesday), which says we wanted to play trumps on 'Rockstar', but this is really not the case. The song was meant to be like that, so we made that video, " he said.

The song was actually the brainchild of the film's writer Akshat Verma and later Amitabh Bhattacharya penned it and Ram Sampath composed and sang the song, said Imran.

"It's a theme of our film. I feel it's the anthem that would come many times in the film, " said the actor, who plays a journalist in the movie.

"I play a journalist in the film. Kunal plays a photographer and the two of us work together. Vir plays a cartoonist. We sometimes get stuck in situations because of our jobs, " he said.
