The latest buzz in K-town is that Rajinikanth and Kamal Haasan, the two top stars of Tamil cinema, will mark their presence felt at the music launch of Dhanush-starrer '3', which is to be held in Chennai soon.

No prizes for guessing the reason, as the film is the directorial debut of the Superstar's elder daughter Aishwarya R Dhanush, while the Ulaganayagan’s elder daughter Shruti Haasan is the leading lady of it.

"The two icons of Kollywood will attend the audio launch of 3. This will take the film, which is already popular thanks to the stupendous success of 'kolvaeri' song, to greater heights,' sources in the know say.

With music composed by newcomer Anirudh, '3' is a love story that is expected to hit the screens early next year. "Though we are a couple, we treat ourselves thorough professionals on the sets. She does what a director has to do and I do my job as an actor," says Dhanush.
