Bollywood superstar Salman Khan has been successfully hosting reality TV show Bigg Boss for the past three seasons but reports are that the actor might not be able to do so this year. According to reports, the Dabangg actor is very busy with his movies this year and may have to opt out of the show. And if rumours are to be believed the show's producers may then approach Salman's arch-rival Shah Rukh Khan to add his charm and wit in hosting the successful reality show. Salman's home production Mental has been delayed due to his court appearances and his medical checkup, as a result he actor's schedule has gone haywire. Bigg Boss is likely to go on air at the end of this year.
