Megastar Amitabh Bachchan got nostalgic when Pakistani actor Fawad Khan came on the sets of his quiz show "Kaun Banega Crorepati" (KBC) to promote his first Bollywood film "Khoobsurat".

Amitabh shared his strong and personal connection with the neighbouring country. Big B revealed that his grandfather was from Karachi and said he had visited that place for the first time with his mother when he was just two years old.

Meanwhile, curious Amitabh also bombarded Fawad with a string of questions like how different is the cinema there and about his fans.

Fawad was accompanied by his "Khoobsurat" co-star Sonam Kapoor.

The episode will be aired Thursday at 8.30 p.m. on Sony TV.
