"While Raghu will be seen hosting the grand finale episode, Kangana and Madhavan will add a fun spirit as they will come to promote their upcoming film 'Tanu Weds Manu Returns'," said a source.
Adding a fiery twist to the final episode, Kangana will also be seen cooking with 'charming assistant' Madhavan.
Raghu, who found fame with the youth-oriented reality show "MTV Roadies", has been part of the cooking reality show in the past in "MasterChef Season-1" and "Junior MasterChef".
