After Amitabh Bachchan announced that he will be hosting the fourth season of Kaun Banega Crorepati? for Sony, the officials of Colors are busy trying to fill his place in the fourth season of Bigg Boss.

The buzz in the industry is that their first choice is Aamir Khan, who is yet to host any show on television. However, Aamir has rejected their initial offer. The channel officials have now apparently raised their offer, hoping Aamir will agree.

Meanwhile, they have also made overtures to Shah Rukh Khan. But even if SRK does agree, it will cost Colors heavily, as they will have to remunerate him to break his contract with Star Plus and match his high fee for every episode he hosts.

Colors has also approached Sanjay Dutt, but if rumours are to be believed, Sanjay has refused the offer as he feels the remuneration is not worth the trouble.

Arshad Warsi and Shilpa Shetty have hosted the first two seasons of Bigg Boss respectively.
