I think Tanisha is a guest in BB7 because early this year I read in a news paper that the BB was offering Amisha Patel the BB7 show as a guest, but due to her busy schedule she did not take it. later on BB offered this show to Tanisha, Therefore, I'm guessing that she is a guest and may be later on after two more weeks BB will ask her to leave the show due to her mother's health just like last year for Sidhu ji and I was correct that time too that he was a guest.
