Thurman gave birth July 15, but inexplicably waited til now to give an indifferent world her name: "I would like to announce Uma and Arki’s daughter’s name for the first time officially: Rosalind Arusha Arkadina Altalune Florence Thurman-Busson," Thurman's rep tells People. "Each name has a special reason and meaning to her mother and father." Fortunately for the kid, her family is calling her simply "Luna." (More Uma Thurman stories.)
