Natalie Portman Venice Aleph

Natalie Portman's son, Aleph, is only four months old, but he's already learning about religion!

The new mom took Aleph to synagogue on Saturday. Then again, "Aleph" is the first letter of the Hebrew alphabet -- so the little one was born with his religion made clear! The name's meaning in Judaic Kabbalah relates to the origin of the universe, the "primordial one that contains all numbers."

And Natalie's clearly seeing how busy motherhood can make someone -- she came to synagogue with wet hair and no makeup!

Luckily, the Oscar-winning actress is gorgeous no matter what! Meanwhile, we spotted Portman's fiance, and Aleph's dad, Benjamin Millepied, out separately! See him in our video below.
