The four challengers have already been revealed. Ajaz Khan is already in the house whereas Rahul Mahajan, Mahek Chahal and Sambhavna Seth will enter the house on 2 January (20150.

“There’s a high chance of Sana being the fifth challenger. However, final decision is yet to be taken,” said a source.

When we buzzed Sana, she denied the development. A channel spokesperson did not revert to our query.

As we all know, the Hallo Bol series will be anchored by Farah Khan and not Salman Khan.
