The 30-second-long clip starts with a man and woman in the Bigg Boss house stuck with each other in a shirt, while Salman laughs at their plight.
The 49-year-old "Bajrangi Bhaijaan" star then says, "Here, one will trouble the other because one plus one is double trouble. This time it will be wow."
Not many details are out about the concept. The montage shows the name of the ninth season as "Bigg Boss Double Trouble".
Salman, who had been hosting the show from past five seasons, quit after the last installment was extended into a limited series called "Bigg Boss Halla Bol". Filmmaker Farah Khan filled in for the extended version.
The new season will once again revolve around a group of celebrities holed up in a house for three months with multiple cameras watching their every move.
