Actor Salman Khan will reportedly play a double role for the upcoming promo of his reality TV show Bigg Boss. The 47-year-old actor will shoot a special promo for the seventh season of 'Bigg Boss', where he will be seen in a double role similar to his 1997 hit comedy Judwaa. In the promo, one character is sophisticated whereas the other one is a street-smart rogue. "Salman will be seen in a double role, like his 'Judwaa' act, in the promos. He will shoot for it soon. We are trying to make it special," a sources said. The show will go on air in September. It is being hosted by Salman since its fourth season.
