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!

Uma Thurman and her children Maya and Levon were spotted taking in the sights of Paris over the weekend, and after visiting some tourist hotspots, the Uma treated her son and daughter to ice cream and lollipops. So that's the trick to keeping your kids happy when touring museum after museum...

Yesterday we spotted Uma Thurman running errands in Beverly Hills, and we can't believe she stepped out with her toes exposed! Not only was it pouring rain in southern California yesterday, but this weekend the temps have hit record lows!

Anyway, forget Uma's frozen feet -- we're dying to know more about Kill Bill 3! Quentin Tarantino has already confirmed that both Thurman and Kill Bill 1 & 2 co-star Daryl Hannah will appear in the film, and while it has a 2014 release date, production could begin as early as this year. Tarantino hasn't revealed what the focus of the film will be, but with the bride and Elle Driver, we're SO in!

Uma Thurman, who was wearing a revealing bikini while vacationing with boyfriend Arpad Busson in Italy, looks as if she may be pregnant with her third child.

The actress, who has two children from her previous marriage to Ethan Hawke, previously broke off her engagement to the billionaire Busson last year, but they reconciled soon after.

And how! The 40-year-old Thurman has never looked happier and healthier -- but is that a pregnancy glow she's sporting or just the look of love? (We've e-mailed her rep for confirmation, but as Thurman's on vacay in Italy, she couldn't be immediately reached for comment.)

Thurman and her maybe baby bump dined with Busson at restaurant The Little Mermaid in Filicudi yesterday before taking a dip off the side of their yacht.

Busson also has two children from his marriage to model Elle Macpherson.
