Madonna: Call Me Esther

The queen of reinvention has done it again. Madonna tells ABC News’ ’20/20′ that she has taken on the Hebrew name of Esther, explaining that, “I was named after my mother. My mother died when she was very young, of cancer, and I wanted to attach myself to another name.” She also talks more about her study of Jewish mysticism known as Kabbala, which she believes is “incredibly punk rock” and anti-establishment. Watch Cynthia McFadden’s exclusive interview with Madonna on ’20/20′ Friday night at 10 p.m. ET/PT.
