The trailer of the much-awaited "Dabangg 2", a sequel to the 2010 blockbuster "Dabangg", will be launched on reality show "Bigg Boss 6", which is hosted by the film's lead actor Salman Khan.

Arbaaz Khan, the producer and director of "Dabangg 2", will join his elder brother Salman Friday on the sets of "Bigg Boss 6" to launch the trailer, a source told.

The special episode will be telecast on Colors Saturday.

"Dabangg 2" will see Salman return as corrupt policeman Chulbul Pandey, and Sonakshi Sinha once again plays his wife. Southern star Prakash Raj plays the antagonist.

Arbaaz's wife Malaika, who gyrated to "Munni badnaam" in "Dabangg" is said to have done an item number for the sequel. Kareena Kapoor too will be seen in an item number.

The movie is slated to release around Christmas this year.
