Ranveer Singh will be seen promoting his forthcoming historical-romance film `Bajirao Mastani` on the popular reality show `Bigg Boss Nau`.

While his co-star and rumoured girlfriend Deepika Padukone promoted her romantic-drama film `Tamasha` last month on the Colors' show, Ranveer will enter the `Bigg Boss` house without her.

He will be seen finding his partner in the house, where all the female contestants will face a quest to become Ranveer's `Mastani`.

The episode of `Bigg Boss Nau` featuring the `Band Baaja Baaraat` actor will be aired on Sunday.

`Bajirao Mastani`, which has been directed by Sanjay Leela Bhansali, also stars Priyanka Chopra.

It will release on December 18.
