Uma Thurman reveals her new daughter's name!

Uma Thurman has revealed her daughter's super long name.

The Kill Bill actress, 42, has unveiled the name of her baby girl, who she and Arpad Busson welcomed in July - and it's a mouthful.

Thurman's representative Gabrielle Kachman told People Magazine:

"I would like to announce Uma and Arki’s daughter’s name for the first time officially: Rosalind Arusha Arkadina Altalune Florence Thurman-Busson."

According to Thurman's rep: "Each name has a special reason and meaning to her mother and father."

The couple have even chosen an unlikely nickname for the little girl. Kachman revealed that the baby is 'better known to family and friends as Luna'.

Luna is Thurman and Busson's first child together.

The actress also has children Maya Ray and Levon from her marriage to Ethan Hawke, while Busson has sons Flynn and Cy with ex-fiancee Elle MacPherson.

Insiders told Us Weekly that Thurman was not originally planning to have another child, but explained of the then-pregnant star:

"It was a surprise, but she’s over the moon about it, very excited."
