The celebrity contestants nominated for eviction this week include Gulab Gang leader Sampat Lal, controversial cartoonist Aseem Trivedi, model Karishma Kotak and hairstylist Sapna Bhavnani.
They will be told about the double eviction on Monday's episode, said a source.
The reality show began with 15 contestants, and so far three of them -- Bhojpuri actor Dinesh Yadav, commoner Kashif Qureshi and actress Sayantani Ghosh -- have already been voted out by the viewers.
Around 5,000 marchers, led by Republican Party of India chief Ramdas Athavale, went up to the "Bigg Boss" home in Lonavala Oct 25, demanding eviction of Trivedi, who had earlier grabbed headlines for sketching cartoons denigrating Indian constitution and other symbols.
The final result will be announced Friday on Colors channel.
