Kill Bill actress Uma Thurman is engaged to her boyfriend Arpad Busson.

A representative of Uma’s has confirmed to a magazine that rumours she has decided to marry her Swiss partner are indeed true.

According to the magazine, Arpad proposed her with an eight-plus carat ring surrounded by 20 smaller stones.

She was seen with the large diamond ring at Elton John’s tenth White Tie and Tiara Benefit in Windsor.

An onlooker told a newspaper that all the ladies were wide-eyed because the ring was so massive! It was so huge that she can’t fit it through the sleeve of her coat.
