Uma Thurman & Fiance Arki Busson SPLIT - Uma Dumped?

Cindy Adams has news Tuesday - that Uma Thurman has split (perhaps been dumped?) from fiance Arpad "Arki" Busson.

From Cindy:

Things were great. And then they weren't. Possibly, just possibly, one reason was Arki was super-rich. Was. Maybe still a little bit is. But for sure, was. This Swiss moneyman lost a bundle in Operation Madoff. It was rumored he could lose Uma. In any case, she recently told me mommyhood had forced her to table career offers and she wanted back to work.

Whatever, came a spat. She walked out in a huff. There was no serious intent to break up, but it made the other side think this engagement should maybe be broken off. So she drew first blood, but it was only a nick. He killed it off, and the waltz has ended. Quietly. And politely. As happens in that small circle of the world's most privileged beings.

People has since reported the same thing, but they are less clear on who did it or why.

Arki was previously engaged to and has two sons with Elle Macpherson, who live in London. Uma was previously married to and has two kids with Ethan Hawke and lives in New York. Neither could move countries full time because of the kids.
