Uma Thurman and Arpad Busson reveal baby girl's name

Actress Uma Thurman and her boyfriend, Arpad Busson, have been keeping their daughter's name a secret since she was born on July 15, but now the extremely long moniker has been revealed.

"I would like to announce Uma and Arki's daughter's name for the first time officially: Rosalind Arusha Arkadina Altalune Florence Thurman-Busson, better known to family and friends as Luna," Thurman's rep tells People magazine. "Each name has a special reason and meaning to her mother and father."

No word on exactly what those special reasons and meanings are.

Little Luna is the first child together for Thurman and Busson. Thurman has two children with ex-husband, Ethan Hawke -- Maya Ray, 14, and Levon, 10. Busson also has two children, Flynn and Cy, with ex-fiancée Elle MacPherson.
