Thurman and multimillionaire fiancé break up

Uma Thurman is single again, it has been announced.

The 'Kill Bill' star and multimillionaire hotelier Arpad Busson have reportedly ended their year-long engagement following a row over money.

A source said: “The engagement ended awhile back – almost two months ago. They remain friends."

According to New York Post columnist Cindy Adams, the couple had a small argument which led to the American actress suggesting the engagement should be broken off, without really meaning it.

Uma then walked out "in a huff" but the spat caused the businessman to rethink their future together and he called time on their relationship.

The couple started dating in the summer of 2007 and became engaged a year later, with Arpad presenting the actress with an eight-carat diamond engagement ring – which she is returning to him.

A source said: "She will probably give it back. She wants to return everything that is his."

Uma – who has 11-year-old daughter Maya and seven-year-old son Levon with ex-husband Ethan Hawke and was also previously married to actor Gary Oldman – recently admitted she was not ready to marry again.

She said: “I’m happily engaged but we haven’t set a wedding up. 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."
