Kaun Banega Crorepati Season 4 is at its finale week and this is going to be a star studded week for the quiz show hosted by megastar Amitabh Bachchan.

In tonight's episode, the viewers will get to see Khele Hum Jee Jaan Se star Deepika Padukone and the film's director Ashutosh Gowarikar cheering the contestants along with some other former contestants of this season.

Deepika would be in her best gracious form in a long pink salwar. She will come on the set of KBC 4 as an epitome of a beautiful Indian woman.

Ex-contestant Rahat Taslim, who became the first woman to win Rs 1crore at KBC, will also come in tonight's episode to encourage the contestants. Apart from her, other ex-participants like Saiba Bajwa and Rajesh Chauhan will also grace tonight's episode.

However, none of the celebrity guest will be quizzed by the host Big B. Prashant Batar, who was the first contestant of the season to reach one crore question, will be seen interacting with Amitabh Bachchan. Batar is again a huge fan of Deepika and he nurtures this secret wish of going on a trip to Antarctica with the actress. This definitely amuses the actress and they had fun chit chatting with each other.

The entire cast of recently launched show 'Saas Bina Sasural' will also join tonight's episode of KBC. Son, don't miss tonight's eventful grand episode of 'Kaun Banega Crorepati' on Sony TV at 9pm.
