Day 100 of "Bigg Boss 9" started with Bigg Boss announcing a fun task -- Secret Disco -- where the housemates had to put on headphones and dance continuously with their respective partners. The contestants were seen thoroughly enjoying the task.
Amidst the fun, three ex-contestants Yuvika Chaudhary, Nora Fatehi and Gizele Thakral entered the house to distract the contestants from performing the "Secret Disco" task.
Yuvika's entry had put a smile on Prince's face. She confronted him by asking if his proposal to her was just a part of his game. Yuvika further said that although Prince and Nora Fatehi make a good pair, she and Prince could have had a good future had he not got involved with Nora. But to Yuvika's surprise, Prince ensured her that he is loyal towards her and that everything else does not matter to him.
Yuvika appreciated Rishabh by saying that he played like a gentleman. She also agreed to dance with him in the grand finale.
Nora, on the other hand, confronted Prince and was seen upset about his fluctuating interests, while Gizele Thakral spent most of her time with her "Kyaa Kool Hain Hum 3" co-actress Mandana. In the evening, all the ex-contestants bid adieu to the housemates.
Later, Bigg Boss organised a daawat for all the housemates except Rishabh, since he was declared as the worst performer of "Secret Disco" by the housemates. Calling it unfair, the inmates rejected the offer as they did not want to have the food without Rishabh. While everyone stood by the decision, Rochelle Rao kept urging Bigg Boss to bring the food.
