After all the buzz that superstar Shah Rukh Khan is going to host the next season of "Bigg Boss", it is now confirmed that his arch rival Salman Khan has been roped in to replace megastar Amitabh Bachchan for the fourth season of the popular reality show.

"Salman Khan has been finalised as the host of the next season. We will announce the development officially soon," a source from entertainment channel Colors told IANS.

"Bigg Boss" is the Indian version of popular British reality show "Big Brother". It has celebrity contestants locked in a house under the surveillance of multiple cameras for a period of three months without any contact with the outside world.

Its past three seasons were hosted by Arshad Warsi, Shilpa Shetty and Amitabh, respectively.
