Amitabh Bachchan has received compliments galore during his prolific career, but a one-liner from actress Kareena Kapoor left him blushing on the sets of "Kaun Banega Crorepati 2013".

Kareena and her "Gori Tere Pyaar Mein" co-star Imran Khan made an appearance on the reality game show to promote their forthcoming film.

During the game, Kareena told Big B: `You are my favourite, Amit uncle.`

This compliment put a big smile on the thespian's face and he hugged Kareena, with whom he has shared screen space in "Kabhi Khushi Kabhie Gham".
