Day 99 of "Bigg Boss 9" started with the housemates waking up to Sunny Leone's song "Laila".

Keith Sequeira and Rochelle Rao discussed about Rimi Sen's prediction that Prince Narula, Mandana Karimi and he will be the finalists of the season.

As the day progressed, Bigg Boss gave Rochelle a secret task, wherein she had to wear micro headphones and complete a set of challenges given to her. Following this, Rochelle got instructions from Sunny Leone, to plant a kiss on the cheeks of Prince and Rishabh Sinha and flirt with them.

She further challenged Rochelle to pick up an argument with Mandana and have a pillow fight with Keith. Not just that, the "Baby Doll" star also demanded Rochelle to bark like a dog in the middle of a conversation with the housemates.

Rochelle had to complete the challenges without letting the inmates get a hint of tasks.

Rochelle left the housemates in shock when she flirted with the boys and Keith too was upset with Rochelle's behaviour. However, he later told Rochelle that he is not bothered by her behaviour towards Prince and Rishabh, as he trusts her a lot.

In the evening, the housemates were overjoyed to see Sunny inside the house. The "Pink Lips" star revealed Rochelle's secret task, which left everyone stunned as she was convincing in all the tasks.

Sunny, who was inside the house to promote her film "Mastizaade", raised the hotness quotient by engaging the contestants in some fun activities.

The female contestants -- Mandana and Rochelle -- had to perform a car wash task and the boys --Keith, Prince and Rishabh -- had to pick up the hottest girl. All the three boys chose Rochelle as the hottest girl, which left Mandana upset.
