Saif Ali Khan, Deepika Padukone to appear on 'KBC 5'

Bollywood stars Saif Ali Khan and Deepika Padukone are set to appear as special guests on the upcoming fifth season of Kaun Banega Crorepati, said megastar Amitabh Bachchan.

Bachchan, 68, will host the show for the fourth time, which is scheduled to go on air from August 15.

"The second episode towards the evening will have invites to Saif and Deepika... who come to promote their film and mine as well - Aarakshan!" wrote Bachchan on his blog.

"In many ways the philosophy of the film and that of KBC is quite similar. Given the opportunity, even the lesser privileged shall prosper. Or at least have the capacity to prosper," he added.

Directed by Prakash Jha, Aarakshan will see Bachchan portraying the role of Prabhakar Anand, a principal, who is against reservations in the education system. The socio-political film is set to release on August 12.

Khan had earlier appeared with actress Preity Zinta in the second season of the show, while Padukone came as a guest last year although she didn't play.
