"Talaash" director Reema Kagti has denied that Rajinikanth is being roped in for a song-and-dance sequence in the movie -- a rumour that has left the legendary superstar's camp flummoxed.

Rajinikanth's associates have informed that he isn't amused with the news either.

Asked if Rajinikanth is turning into an item boy for the Aamir Khan-starrer, Kagti said: "Not true."

In the meantime, the iconic actor is busy with his southern project.

A source said: "At the moment Rajiniji is completely involved with every department of his new film 'Kochadaiyyan'. He is not even looking at doing any other work. He spends all his time with the post-production team.

"He is helping his daughter (Soundarya) with the editing, mixing, background score. Most of all, Rajiniji wants to make sure that the special effects for the action sequences come out perfectly. For that he insists on flying out with the technical team to London each time they need to work on the effects."

The 61-year-old's associate said: "At first Rajiniji's family took the rumours of an item song in their stride. But now the reports are getting increasingly inventive."
