Penelope Cruz and Javier Bardem are over the moon with the arrival of their newest baby girl -- quite literally. The silver screen pair named their daughter, born July 22, Luna Encinas Cruz. Luna, in Spanish, means moon. Encinas is Javier's paternal surname and translates as live oak, notes Daily Mail. Luna was born at the Ruber Internacional Hospital in Madrid, Spain, and is the pair's second child -- they have a two-year-old son, Leo. Despite their fame, Bardem and Cruz have always been extremely protective of their private lives. "I want my son -- and my kids if I have more -- to grow up in a way that is as anonymous as possible," Cruz told Vogue in 2011.
