Bollywood megastar Amitabh Bachchan or Big B as we all love to call him has been one of the most popular faces in the small screen as well. With the fourth season of Kaun Banega Crorepati almost coming to an end, there are quite a few celebrities who are expected to be invited to join in the show in the episodes that are to be aired during the last week.

However, as is the rule these days, most movies that release, come on reality shows on the various channels to promote their films. The main cast along with the director generally goes for such shows. So was going to be the case for the Ashutosh Gowarikar film Khelein Hum Jee Jaan sey which has Abhishek Bachchan and Deepika Padukone in the lead roles.

The cast of this film are also to be coming in to answer questions from the hot seat as Big B sits and grills them on so that a few bucks can be earned by the team, which is generally donated for a cause.

Reportedly, Big B did not give permission to his son Aby Baby or Abhishek Bachchan to join in the promos of the film on this show.

But why did Big B bar Aby baby from participating in KBC?

Well the buzz doing the rounds is that since the Kaun Banega Crorepati contract that Amitabh Bachchan had signed with the authorities has a clause which states that none of his family members would be allowed to take part in the show. Thus, being a thorough gentleman, Big B did not think it would have been right if Abhishek Bachchan would have come on the show, even if it was only for the promotions of the film.

Now, that pretty much explains why Aishwarya Rai Bachchan had not participated in the show earlier when Vipul Shah's film Action Replayy was being promoted in the show.

Well, when it comes to following principles who can ever beat Big B?
