Uma Thurman's Daughter has 51-Alphabet Name

Uma Thurman has finally revealed her baby's name three months after giving birth.

"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's rep Gabrielle Kachman told People magazine.

However, the couple hasn't revealed the inspiration behind their baby's name.

"Each name has a special reason and meaning to her mother and father," the rep told People magazine.

This is the first child for the 42-year-old and her boyfriend Arpad Busson. Thurman is already mother to two children from her second marriage to actor Ethan, 14-year-old Hawke-Maya Thurman and 10-year-old Levon Green Hawke.

She got engaged to London-based business man Busson and announced expecting a baby in February this year.

Though the third pregnancy was unexpected, the "Kill Bill" actress was overjoyed with the news.

"Uma was definitely not planning on having another kid. It was a surprise," a source told Us Weekly. "But she's over the moon about it, very excited."
