Halevi is the second oldest of six children. She was born in Rosh HaAyin, Israel. Her parents are a teacher and a retired firefighter. She is a Yemenite Jew whose grandparents immigrated to Israel from Yemen.[8] She attended Orthodox girls school as a child. She used to write and perform small plays each month for Rosh Chodesh. “I don’t remember a time when I didn’t want to be an actor,” she said. “It’s the need to be loved and liked, wanting people to look up to you in some way. It’s a validation.”.[8]
Halevi completed her one year mandatory military service in the Israeli Defence Force at the age of 19. Halevi obtained a work permit during that same year, and she moved to Los Angeles in order to pursue acting. She briefly returned home to Israel. She ultimately "followed her heart", and she returned to Los Angeles the following year.
