Uma Thurman has finally revealed her 3-month-old daughter's name, and we have to say ... it's not quite like anything we've ever heard before!

"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 said in a statement. "Each name has a special reason and meaning to her mother and father."

Thurman and longtime boyfriend Arpad "Arki" Busson welcomed their first child together on July 15. The couple began dating in 2007, but they called off their engagement in 2009, only to reunite in 2011. Uma also has a daughter, Maya, and son, Levon, with ex-husband Ethan Hawke.

For giving birth a mere month ago, she looks unbelievable!

Uma Thurman took her baby daughter to a doctor's appointment in New York City today, and the Kill Bill actress opted to go makeup-free on the excursion. We don't know a lot of women who would leave the house fresh faced, but when you look this good why not?!

The little one's name has yet to be released, so hopefully we find out soon!

Ethan Hawke's ex has been dating baby daddy Arpad Busson since 2007. The pair were engaged for a period of time, but called off the wedding in 2009, only to reunite again in 2011.

Now that they have a child together, let's hope these two are in it for the long haul!

Uma Thurman and boyfriend beau Arpad Busson welcomed a baby girl on Sunday, according to a source for Us Weekly.

Uma has two children, Maya, 13, and Levon, 10, with ex-husband Ethan Hawke, and this is her first child with Busson, who she's been with off and on since 2007. The two got engaged in 2008, and despite calling off their engagement in 2009, they reunited last year.

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

No word on what Uma is planning on naming her bundle of joy, but we'll keep you posted!

She may be sporting a growing baby bump, but that's not stopping Uma Thurman from taking a dive into the ocean!

The 41-year-old Kill Bill actress has been vacationing in St. Barth since last week, and yesterday she was snapped taking a refreshing dip off of beau Arpad Busson's private yacht. Thurman and Busson revealed last month that they're expecting their first child together, and she already has two kids from her marriage to Ethan Hawke, Maya and Levon.

Looking maternity-chic in a bright green maxi dress, black strappy sandals and a Louis Vuitton tote, Uma Thurman fed her pregnancy cravings with a sweet ice cream treat while on holiday in St. Barths, on Monday afternoon.

The Kill Bill star is currently enjoying a luxurious vacation in the South of France with her 13-year-old daughter, Maya, and 10-year-old son, Levon, where they've been cruising A-list style on a luxury multimillion-dollar yacht.

Thurman, who is expecting her third child this summer, was showing off her growing baby bump in a tiny two-piece bikini over the weekend, alongside her French-born financier boyfriend Arpad Busson.

The Oscar nominee recently dished to Harper's Bazaar on her love life, "I have something I would really like to express about my love life. I’m happier with it now than I’ve been in many, many years. Yes I’m trying to have as peaceful a personal life as possible."

Bumpin' beautiful!

Treating her baby-to-be to a luxurious yacht ride in the South of France, Uma Thurman covered up in a nautical-chic striped bathing suit as she took a dip in the ocean, on Saturday afternoon.

But Thurman did show off her massive baby bump in a teeny black bikini in St. Barths over the weekend, where she's vacationing with 13-year-old daughter Maya, and baby daddy Arpad Busson.

The Kill Bill star is enjoying all the down time she can get now, because her upcoming period drama Bel Ami, costarring Robert Pattinson, hits theaters March 27!

It was just last month that Uma Thurman and hubby Arpad Busson announced they were expecting their first child together, but it seems like the actress is ready to give birth before Easter!

Uma and her daughter Maya were spotted in St. Barth yesterday, and the ladies didn't have a care in the world as they took a dip in the ocean. Uma later tried to sit up and read on the beach, but her baby bump is getting so large, it seemed a bit impossible!

Uma Thurman and beau Arpad Busson are expecting their first child together, a rep for the 41-year-old actress has confirmed.

Thurman and Busson, a London-based financier, began dating in 2007, and they got engaged in June of 2008. Though the couple split briefly in 2009, they rekindled the romance shortly thereafter.

Thurman has two children, Maya, 13, and Levon, 10, with ex-husband Ethan Hawke.

Congrats to the expectant parents!
