Neta Barzilai had to cancel the events she was supposed to perform in. The person chosen to replace her is none other than Shiri Maimon.
She also appeared at Eurovision in the past, in a performance that was No less successful and better than BarzILai's. She is now at home and recovering, but the schedule, of course, had to change. Celebs are always on stand-by, but for some reason were never called to change on stage.
