Actress Preity Zinta along with co-judges of dance-based reality show Nach Baliye 7 - author Chetan Bhagat and choreographer Marzi Pestonji - gave a surprise visit to the grand finale of `MasterChef India 4`.

As the `Nach Baliye 7` shooting was taking place next door, the trio decided to pay a surprise visit on the set of the cooking-based reality show, which is heading towards its grand finale on Sunday with three finalists- Neha Shah, Bhakti Arora and Nikita Gandhi.

The three judges of `MasterChef India-4` - Sanjeev Kapoor, Vikas Khanna and Ranveer Brar - were pleasantly surprised by the visit.

`It was a pleasant surprise to see the 'Nach Baliye' judges on our set. This was not planned and we had a lot of fun. Our finalists Neha, Bhakti and Nikita were thrilled to no extent," Kapoor said in a statement.

According to a source from the set, Bhagat was seen saying that the common factor between food and dance is that both are done from the heart. Bhagat even made Khanna learn some dance moves from Pestonji.

`Nach Baliye 7` will be aired from April 26 on Star Plus.
