Why does Shah Rukh want to enter Salman's house?  

Apparently, Shah Rukh Khan intends to promote his upcoming film Dilwale on 'Bigg Boss', the show hosted by his friend Salman Khan, after the latter stated that the former was more than welcome to be a part of his show.

Details of the promotions are still being worked out, apparently, but news reports suggest that Shah Rukh will join Salman a week from now to shoot for the episode. His co-stars from the film, including Kajol, are supposed to join in too for the episode that may air a week before the season's finale in December.
