Uma Thurman's baby's name? Call her 'Luna' for short

Celebrities are known for selecting some interesting names for their children, but this one is one of the longest ones that's been announced in a while.

Uma Thurman, 42, and beau Arpad Busson, 49, a London-based French business exec, have taken months to publicly reveal their daughter's name. The baby was born July 15, but now we finally know her name — her full name.

Are you ready? Here it is:

"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," the actress' rep Gabrielle Kachman tells People.

"Each name has a special reason and meaning to her mother and father," Kachman says, without elaborating.

Luna, who was born in Rhinebeck, N.Y., joins elder siblings Maya Ray and Levon Thurman-Hawke, from Thurman's marriage to actor Ethan Hawke, and Flynn and Cy Busson, his sons with model and ex-fianceé Elle MacPherson.
