Welcome, little Luna! Penelope Cruz and Javier Bardem named their new baby girl, who was born on July 22 in Madrid, Luna Encinas Cruz, according to Spanish magazine, Vanitatis. The actress' rep did not immediately respond for comment.

The magazine reports that Bardem, 44, visited Madrid's registrar office on July 30, where he registered their new bundle of joy. 

So what's behind the little one's moniker? Well, Luna means moon and the name takes on both her father and mother's paternal last names. (Encinas is Bardem's first surname.)

Cruz, 39 and the Spanish-born actor, who wed in July 2010, are already parents to their 2-year-old son Leonardo.

They confirmed they were expecting again in February 2013, with the Oscar-winning actress telling Spanish TV station TVE! that she is "tremendously happy and excited" about having a second baby.
