Uma Thurman became a mom again back in July, welcoming her first baby with boyfriend Arpad Busson on July 15th. Until now, however, the couple has kept their new daughter’s name to themselves. The wait may have been long, but the name is even longer! Baby girl’s official name is Rosalind Arusha Arkadina Altalune Florence Thurman-Busson, but her family calls her Luna. Between Thurman and Busson, Luna has four older siblings: Maya Ray and Levon Thurman-Hawke and Flynn and Cy Busson.
