When Bigg Boss broke the news to Karishma, she broke down and opted to leave the house in order to be with her bereaved family.
Mink Brar will now step into the house on Saturday, November 3.
Mink was discovered by Dev Anand, who launched her in the 2003 movie Pyar Ka Tarana.
She has done a couple of reality shows on television earlier.
Meanwhile, former Bigg Boss contestants Dolly Bindra and Shweta Tiwari have been approached to enter the house as guests.
