Uma Thurman is engaged and has a mighty big ring to prove it.

The Kill Bill star broke the news in none other than the wedding section of the UK's The Times newspaper. In last week's Saturday edition of the paper, it read "The engagement is announced between Arpad, son of Mr Pascal Busson, of Paris, and Mrs Florence Harcourt-Smith, of South of France, and Uma, daughter of Mr and Mrs Robert A. F. Thurman of New York."

Uma's fiance is Swiss multimillionaire Arpad "Arki" Busson. He was previously married to supermodel Elle Macpherson. This will be her third trip down the aisle - her first marriage was to Gary Oldman and then to Ethan Hawke whom she divorced in 2003.

According to the papers, her engagement ring is a mega-rock - an 8-plus carat center stone surrounded by 20 smaller stones. One report in the New York Daily News, quoted a source saying "it's so big, she can't fit it through the sleeve of her coat".
