Anyone who thinks Uma Thurman’s still pining away for her ex and the father of her two children while he cavorts with their former nanny is dead wrong. The actress just confirmed her engagement to millionaire/hedge fund financier Arki Busson. Take that, Ethan!

Uma Thurman is engaged to her Swiss multimillionaire boyfriend, Arpad “Arki” Busson, her rep confirms to PEOPLE.

“I can confirm she is engaged,” Stephen Huvane said on Friday.

In return for saying yes, the actress received some serious sparkle: an 8-plus carat center stone surrounded by 20 smaller stones. “It’s the most beautiful piece I’ve ever seen,” says a close source of the diamond ring. “Arki did a wonderful job.”

The pair began dating last summer after attending a private dinner together in Milan. Since then, their relationship quickly heated up despite the fact that the couple lived on different continents (she is based in New York, he in London).

It would be the second marriage for Thurman, who has a son and daughter with ex Ethan Hawke, whom she divorced in 2003. Busson has two sons with former supermodel Elle Macpherson, from whom he split in 2005.

No wedding date has been set.

Actually, this would be Uma’s third marriage - before Ethan, she was married to actor Gary Oldman from 1990-1992. Congrats to the couple, and let’s hope this marriage works out for Uma.

Picture note by Celebitchy: Uma Thurman and Arpad Busson are shown at Nelson Mandela’s birthday dinner on 6/25/08, and at “Wings Worldquest 2008 Women of Discovery Awards Gala” on 3/5/08, thanks to WENN. Uma did not appear to be wearing the ring on Wednesday night, and just had a simple band on her left ring finger.

Uma Thurman, 37, is rumored to be engaged to her new boyfriend, Swiss millionaire investment banker Arpad Busson, 44. He was said to have proposed in early October after just a few months of dating, but if that’s true he either didn’t give her a ring or she’s not wearing it out. She has been seen out since, including her infamous appearance at Fashion Rocks in a see-through dress, and she isn’t wearing an engagement ring.

Now Star reports that Uma has asked Arpad to move in with her in NY. He is said to have a home base out of London, so maybe it would be more convenient for her if he’s staying with her while he’s in NY:

After just three months of dating, Uma Thurman has asked multimillionaire financier Arpad Busson to move into her swanky NYC apartment! “Uma likes having Arpad at her side,” explains a friend, noting that Uma and hotelier Andre Balazs broke up “because he always had to work. She doesn’t like being by herself” But Arpad, the father of supermodel Elle Macpherson’s two children, “makes time for her.”

That’s the entire story, so maybe Star is just making it up because there aren’t a lot of details there.

One recent story about Uma that might be true is the claim that she insists on doing her own hair and makeup when she’s on a movie set and refuses professional help. Whitney Bears does that too, but they make it sound like Uma is less stubborn about it and just doesn’t want people fussing over her:

An insider tells Star that whenever Uma works on a movie, she insists on doing her own makeup and styling. In fact, when she starred in the 2005 film Prime, she wore clothes from her own closet. “Uma doesn’t like a lot of fuss,” says the insider, especially when it comes to makeup. “The stylists would try to sneak in touch-ups, and she’d shoo them away.”

Whatever Uma is doing lately, it’s working. She looked positively gorgeous at Fashion Rocks in that gauzy dress that left little to the imagination. Maybe her new romance is giving her a natural glow too.

Uma and Arpad are shown at Petra Nemcova’s Happy Hearts Fund Heart of Gold Ball on 10/11/07. Thanks to Splash News.

Uma Thurman, 37, is engaged to her Swiss millionaire boyfriend, according to reports. They’ve only been together for a few months, but supposedly Arpad Busson, 44, has proposed to the actress and mother of two.

The ‘Kill Bill’ actress, who has only been dating banker Arpad ‘Arki’ Busson since the summer, was said to be shocked and delighted when Arpad proposed to her last week.

A source said: “They have only been together a few months, but Arpad was determined to snap Uma up as quickly as possible. They make a great couple and are totally smitten with each other.”

The couple are yet to set a wedding date or choose a location for the nuptials.

Thurman and Busson met this summer. in July at a dinner in Milan hosted by Gianni Versace and Tony Blair (Update: commentor Jen UK notes that Gianni Versace died in 1997, so they couldn’t have met there. It’s possible the mention of their meeting is taken out of context and applies to Busson and Elle Macpherson, not Busson and Thurman. The Wikipedia entry may have been edited to make it seem as if that sentence applied to the wrong woman.) Busson is an investment banker and earned his fortune through starting his own hedge fund business in 1992. He dated Farrah Fawcett when he was young and was with Elle Macpherson for around three years, fathering two children with her. Busson and Macpherson split up July, 2005.

Wikipedia notes that Macpherson said that Busson would not marry a divorced woman despite having two children with her, as he is a devout Catholic. So either he has changed his mind or this news isn’t true. Thurman divorced her second husband and the father of her two children, Ethan Hawke, in 2004 after rumors of his infidelity with a young Canadian model. She was last linked to hotelier Andre Balazs, and seems to have had a tumultuous relationship with him as there were stories that they broke up several times.

Busson lives in London while Thurman lives in Hyde Park, NY.
