Big Brother Israeli Season 11, also known as HaAh HaGadol 11, premiered on 5 December 2020 on Reshet 13. Liron Weizman and Guy Zu-Aretz co-host the show. In addition, the former housemate, Avivit Bar Zohar, as the “Digital Sister” for this season.
Due to the COVID-19 pandemic, for the first time, official housemates were required to be in quarantine for two weeks rather than normally for two to three days as in previous seasons. The housemates did the first week of quarantine in their own house and the second week in the hotel. In addition, all the housemates must do a corona test before entering the quarantine. There would also be no live audience like last season.
