It will be a double celebration as the fourth season of "Kaun Banega Crorepati" has been scheduled to go on air on Sony TV on Bachchan's birthday. The bash will be held at the J.W. Marriot and will be attended by Amitabh's family as well as some well-known personaities, including film stars and others.

“His family, actors John Abraham, Bipasha Basu and even cricketer Mahendra Singh Dhoni are expected to attend the party. Dhoni might fly down to Mumbai to wish him personally and be a part of the celebrations,” a source from the channel told IANS.

Amitabh's son Abhishek and daughter-in-law Aishwarya are currently at the Pusan International Film Festival in South Korea, where their film “Raavan” is being showcased. But they will be back in time for Big B's birthday.
