People.com Celebrity Uma Thurman Calls Off Engagement She's split from financier fiancé Arpad Busson, though they remain friends, says a pal By Liza Hamm and Bethany Lye Miga Published on December 8, 2009 10:45 AM Share Tweet Pin Email Photo: Sara Johannessen/EPA Uma Thurman is single again. The actress broke off her year-long engagement to Swiss multimillionaire Arpad “Arki” Busson on Nov. 15. “The engagement ended awhile back – almost two months ago,” says a source. “They remain friends.” The couple began dating in the summer of 2007, and one year later, Busson proposed with an 8-plus carat engagement ring. Just don’t expect to see that ring on Thurman’s finger anytime soon. “She will probably give it back,” says the source. “She wants to return everything that is his.” A rep for the actress had no comment. Perhaps their long-distance love affair was a factor. In September, Thurman, 39, admitted she wasn’t planning to marry her London-based fiancé anytime soon. “I’m happily engaged but we haven t set a wedding up,” she told W magazine. “I’m not in a rush to do anything. One day we’ll do it, when we’re ready. We can’t live anywhere else because my children’s father lives here. We’ll figure it out.” Apparently, Busson is “beside himself” that they weren’t able to figure things out. The businessman has two sons with his former flame, supermodel Elle MacPherson, and Thurman has a son and daughter with ex-husband Ethan Hawke. POLL: Which star split shocked you the most?
