Max Liron Bratman marked his first week on the planet by having his bris at the weekend.

The son of singer, Christina Aguilera and hubby Jordan Bratman was officially named (and snipped) at their Beverly Hills home yesterday.

A bris is a Hebrew baby naming and circumcision ceremony typically performed on the eighth day after the child is born. Max Liron, whose middle name means "my song" in Hebrew, was born on Jan. 12 in Los Angeles.
