Bollywood superstar Salman Khan, who will return as the host of popular reality show `Bigg Boss` in its upcoming ninth season, promises `double trouble` in the show`s first promo which was released on Sunday.

Salman Khan shot for the promo in Mumbai on Friday. He took to social media to share a photo from the shoot and tweeted, "Bigg boss season 9 is mine . #biggboss9 promo shoot . @rajcheerfull @ColorsTV"

Salman, 49, hosted the last season of the show, but later stepped down from its extended edition `Bigg Boss Halla Bol` which was hosted by choreographer-filmmaker Farah Khan. At that time, he had to attend to his other film commitments.

The `Dabangg` star has hosted a total of four seasons of the show, which is an Indian version of internationally acclaimed reality format "Celebrity Big Brother". The show involves celebrity contestants locked inside a purpose-built house for three months under constant camera surveillance and with no luxury and limited amenities of life.

On the film front, the `Bajrangi Bhaijaan` actor will next be seen in `Prem Ratan Dhan Payo` but he`s keeping busy by promoting his forthcoming production `Hero`, the title song of which he has crooned himself.
