Natalie Portman, Benjamin Millepied reveal baby name: Aleph
Now a source is confirming to People that Portman and Millepied named their bundle of joy "Aleph" (or, per some other sites, "Alef").
Aleph is the first letter of the Hebrew alphabet and also means the number one. According to Wikipedia, Aleph represents the oneness of God in Jewish mysticism.
