Uma Thurman, 39, has reportedly split from her 46-year-old multimillionaire finance Arpad "Arki" Busson, whom she began dating in the summer of 2007.
"The engagement ended awhile back – almost two months ago,” a source close to the couple told People, "they remain friends."
Uma and Arki announced their engagement last June after Arki proposed with an eight-carat engagement ring surrounded by 20 smaller stones.
"She will probably give it back.” the insider said, “She wants to return everything that is his."
A rep for the actress had no comment yet.
