The second season of Bigg Boss is all set to go on air from August-end, but there's a change in the host. The show, now on Colors, has signed up Shilpa Shetty as its anchor, say reports. She was chosen to replace Arshad Warsi because of her Big Bother experience. She is being reportedly signed on for a whopping Rs 8 crore. Big Boss 2 starts right after the Akshay Kumar-hosted reality show Khatron Ke Khiladi comes to an end.
