A little birdie whispers that the couple who will replace Amir and Sanjeeda are the new love birds Ali Merchant and Sara Khan. But the news comes with a rider that Sara and Ali will only do two episodes. A source from the show says, “Ali and Sara were always the favourite couple of the channel and the production house and the channel wanted to have them on-board as participants. Somehow things didn’t materialise but now the channel has got them to host the show for two episodes. The format of the show has always invited celebrity guest hosts to anchor some episodes.” Sara and Ali though refuted the rumours saying they are not hosting the show. Our source re-confirmed the news and said, “The couple is hosting two episodes of Nach Baliye 4 .” Time and TRP will tell if the new couple will give the necessary fillip to the show.
