Megastar Amitabh Bachchan has shared a few pictures from the sets of R Balki's "Ki & Ka". Big B and wife Jaya will reportedly be making guest appearances in the film, which stars Kareena Kapoor Khan and Arjun Kapoor.

Earlier, there were reports that Amitabh Bachchan would do a cameo in the film, but Jaya Bachchan's appearance came as a surprise to audience.

The reel and real life couple is going to share screen space after 14 years. Last time, they appeared together on-screen in Karan Johar's "Kabhi Khushi Kabhie Gham".

Interestingly, this will be the fourth film after "Cheeni Kum", "Paa" and "Shamitabh" that Big B will be working with R Balki.

"Ki & Ka" has created a lot of buzz since the beginning. The interesting title of the film made fans curious. 'Ki' derived from the word 'ladki' (means girl) and 'Ka' is taken from 'ladka' (means boy).

The film is about a boy and a girl who get married, but their lifestyle is different from regular couples.

In the flick, Kareena will play the character of an independent, career-oriented woman who is the breadwinner of the house. On the other hand, the "2 States" actor will portray a "house husband".

The shooting for the flick has started and the perfectionist director is working hard to make it a masterpiece. Before the shooting commenced, Balki, Arjun and Kareena were ''locked up" in the director's office for a week to rehearse the script.

Nothing much has been revealed about the film as yet, but it has only raised fans' expectations.
