Christina Aguilera and husband Jordan Bratman have introduced their newborn child into Judaism’s roots by celebrating traditional bris. The singer and music producer held the naming and circumcision ceremony of Max Liron Bratman on Sunday to formalize the baby's middle name, which means 'my song' or 'my joy' in Hebrew. The bris is usually done on the eighth day after the birth of the baby and is attended by family and friends.
