Get ready for one of the longest baby names in history.
Since welcoming her third child on July 15, Uma Thurman and her beau Arpad Busson have remained mum on their daughter‘s name. And it was worth the wait.
“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,” Uma’s rep tells PEOPLE.
While the origins of Luna’s name remains private, Uma’s rep says, “Each name has a special reason and meaning to her mother and father.”
Born in Rhinebeck, N.Y., baby Luna is the first child for the actress, 42, and Busson, 49.
She joins big sis, Maya, 14, and Levon, 10, from Uma’s marriage to Ethan Hawke, as well as Flynn, 14, and Cy, 9½, the financier’s sons with ex-fiancée Elle MacPherson.
