Uma Thurman and her millionaire businessman fiancé, Arpad Busson, have split.
A source close to the couple tells Usmagazine.com they called it quits nearly two months ago.
"Uma and Arki are friends," the insider tells Us.
The New York Post's Cindy Adams first reported the news.
Thurman, 39, and Busson, 46, announced their engagement last June after Busson gave the actress an eight-carat diamond ring.
Thurman -- who began dating Busson after splitting from hotelier André Balazs -- has two children with her ex husband, Ethan Hawke. She was also wed to Gary Oldman.
Busson has two children with his ex-fiancée, model Elle Macpherson.
