Why is Imran Khan scared of Rishi Kapoor?

Chocolate boy Imran Khan has performed to the hit number Tayyab Ali in OUATIMD, that was originally performed by Rishi Kapoor with his wife Neetu Kapoor. Imran while stepping out from BR studios saw Rishi Kapoor approaching and was frozen to the spot with fear, as to how the senior actor will react to his performance.

As per sources ,initially he decided to hide then reason prevailed and he stepped forward to compliment Rishi Kapoor for his performance in D Day.But Rishi Kapoor complimented him in return for his new number and said that he never could have imagined his hit song could be redone in such a peppy manner.

Imran Khan after that had a silly grin on his face the whole day.
