Controversial show "Bigg Boss 9" is getting interesting day by day.

While viewers are eagerly waiting for the upcoming episode that will air on Wednesday, according to Twitter buzz, Kanwaljeet Singh sparked controversy when he commented about Keith Sequeira and his ex-wife.

This irked Rochelle Rao, who entered into an ugly spat with the 60-year-old. She warned him not to speak about Keith as he doesn't know him. To this, Kanwaljeet replied that he knows Keith better than Rochelle, which further angered the lady.

It should be mentioned that in the luxury budget task -- Dairy -- wild card contestant Kanwaljeet, who has been friendly with the housemates ever since he entered the house, faced a backlash from them for passing unpleasant comments.

And now with him commenting on Keith, almost all the housemates have isolated him.
