Close on the heels of Aamir Khan singing `Aati Kya Khandala` to his heroine Rani Mukherjee in `Ghulam`, Amitabh Bachchan does the same.

But the only difference is that the heroine happens to his wife Jaya Bachchan. Inspired by Aamir`s song, Karan Johar has decided to let Amitabh sing in `Kabhi Khushi Kabhi Ghum` to his heroine. So the song has Amitabh signing to Jaya. Jaya replies back in equal gusto. We will wait for the promos of the song .
