Uma Thurman and Arpad ‘Arki’ Busson Get Engaged

Uma Thurman and Arpad HOLLYWOOD, Calif. — Uma Thurman is set to walk down the aisle again.

The 38-year-old actress is now engaged to her Swiss financier boyfriend, Arpad “Arki” Busson, according to New York’s Daily News.

Busson, 44, popped the question earlier this week in London, where the couple attended a star-studded 90th birthday party for Nelson Mandela.

“It was a really old-fashioned romantic gesture,” a friend tells the Daily News.

Thurman’s shiny new bling is reportedly so huge “she can’t fit it through the sleeve of her coat,” the friend says.

The couple’s romance began last summer at a private dinner in Milan.

This will be the third marriage for Thurman. She married English actor Gary Oldman in 1990, but they divorced two years later.

The “Kill Bill” star went on to marry actor Ethan Hawke in 1998, after the two met on the set of “Gattaca.” They divorced in 2004 and have two children together, daughter Maya, 9, and son Levon, 6.

Busson was previously engaged to supermodel Elle Macpherson. The former couple, who split in 2005, have two sons together.

Thurman and Busson, who also previously dated Farah Fawcett, have yet to set a wedding date.

“Uma is hoping this time, it’s really love,” the friend says. “Everyone wants the best for her. And Arki is a really sweet guy.”
