When Ajay Devgan decided to make his debut in U ME AUR HUM, he was looking for a young lead actor who would play a crucial role in the film. Incidentally, he didn't get a single actor who would suit the cameo. It so happened that Kumar Mangat was also planning to launch his daughter in a film and he wanted to cast a new comer opposite his daughter. He was impressed by Aditya Singh Rajput aka Addy’s performance that he decided to offer Addy a lead, whenever he made a movie. Meanwhile Kumar recommended Ajay Devgan to cast Addy for the role.
The next day the Delhi boy, Addy got a call from the production house and he was asked to report on the first day of the shooting. Incidentally, Ajay Devgan didn't even take any audition and when Addy asked him, he said, 'Kumarji has recommended your name so I have confidence in you.' This Delhi boy Addy just couldn't believe his luck that he was acting with Ajay Devgan and Kajol.
