Actress Uma Thurman Reveals Long Baby Name

While the couple is keeping the origins of Luna's name private, Thurman's rep allows, "Each name has a special reason and meaning to her mother and father."

Born in Rhinebeck, N.Y., baby Luna is the first child together for Thurman, 42, and [Arpad] Busson, 49. She joins elder siblings, Maya Ray and Levon Thurman-Hawke, from Thurman's marriage to Ethan Hawke, and Flynn and Cy Busson, the financier's sons with ex-fiancée Elle MacPherson.
