Rockstar | Wallpapers | Trailers | Ranbir Kapoor | Ranbir Fan ClubThe Big Boss 5 contestants might possibly get a big surprise soon. Reportedly, they might see actor Ranbir Kapoor and singer Mohit Chauhan making a special entry this week. They will visit the sets of Bigg Boss 5 - Aapka Farman to promote their forthcoming movie Rockstar. But it is still not confirmed if they will enter the house and speak to the contestants in person. If sources are to be believed, Ranbir is very keen to have a conversation with the ladies, and will try and get host, Sanjay Dutt, to help him do so.
