With a name like Kravitz we've always wondered.
Yes, Lenny Kravitz by descent is a half-Jew. His father was of Russian Jewish parentage. His mother was Bahamian.
Kravitz self-identifies as both a Christian and a Jew and says he is a spiritual person.
One of his albums is titled Baptism. He has a back tattoo, "My Heart Belongs to Jesus Christ." He has said, "I'm half Jewish, I'm half black, I look in-between."
His song Another Day, recorded with Michael Jackson, was pulled from YouTube after one day.
