Ranbir and Rishi Kapoor may dance together in a special number

The handsome Ranbir Kapoor and his father Rishi Kapoor may look together in a film for a special song. The combination of both of them would be interesting one when they will dance together on same song and on the same set. Director Siddhaarth showed his desire to shoot a special number for both son and father. But he is feeling nervous while talking about it with Ranbir�s father Rishi Kapoor.

Siddhaarth said, �For the beginning of the song, we used few lines from HUM KISI SE KAM NAHIN by Kishore Kumar. Then rest of the part has been sung by Kishore and Leena Chandavarkar�s son Sumeet as an original composition. This would be little bit emotional.

Bachna Ae Haseeno is counted as one of the excited movie because in this two love birds Ranbir Kapoor and Deepika Padukone Along with hot Bipasha Basu and Minissha Lamba in main roles. For the film Siddharth has signed Vishal-Shekhar for the music of the film. Firstly Siddharth pointed Ranbir to sing a song for the film but later on he didn�t find him fit for the song and he himself dropped that idea. Now Siddharth has held a positive attitude for the success of the film.
