Uma Thurman is to marry her long-term boyfriend Arpad Busson.

The Kill Bill star has been dating the Swiss businessman since last summer and their romance has blossomed, despite living an ocean apart - Thurman is based in New York, while Busson lives in London. But the couple has now decided to take their relationship to the next level after Thurman accepted Busson's proposal, reports People.com.

The actress' representative, Stephen Huvane, says, "I can confirm she is engaged." Thurman was presented with an eight-plus carat diamond ring, with the large center stone surrounded by 20 smaller gems. And the sparkler has been given the seal of approval by a pal of the star.

The source tells the New York Daily News, "It's the most beautiful piece I've ever seen. Arki did a wonderful job." A date for the wedding has yet to be set.

It will be Thurman's second marriage - she split from first husband Ethan Hawke, with whom she has two children, in 2003 - and a first for Busson. The multi-millionaire also has two kids with his ex, supermodel Elle Macpherson. They parted ways in 2005.
