Incidentally, the Kapoor scion was dating Deepika and was linked to Katrina too. Deepika featured in an item number in the just released `Dum Maro Dum` while Katrina`s `Sheila ki Jawani` from `Tees Maar Khan` was hugely popular last year.
The young actor has dedicated the song to father Rishi Kapoor`s `tapori` character from the ever green blockbuster `Amar Akbar Antony` although the genre of his song is completely different, with kids involved in it.
According to sources, although Ranbir is very happy with the final dance number choreographed by Bosco Caesar, he wants to sit and watch the song once again, this time under full scrutiny, and make sure that every little move is impeccable and fun to watch.
The 28-year-old star is doing all this not only because it is his first item number with kids but also because he is apprehensive about the competition his first item number might face from Deepika and Katrina, they said.
