Uma and Arki share a happy moment off the coast of Sicily

Gazing lovingly at one another as they embraced on the deck of a luxury yacht off the coast of Sicily, Uma Thurman and her businessman love Arpad "Arki" Busson couldn't have looked happier.

The Hollywood A-lister and her Swiss fiancé, who announced their engagement in June, snatched the tender moment alone during a trip around the Aeolian Islands, a volcanic archipelago north of Sicily. The busy twosome are currently relaxing with pals, including Oscar nominee Liam Neeson, travelling round the beautiful region.

While the New York Post has reported the couple's summer break is actually their honeymoon, Uma's spokesperson has denied reports the Kill Bill star secretly wed her multi-millionaire love last month in Manhattan.

Uma Thurman is engaged

Uma Thurman and her boyfriend, Arpad "Arki" Busson are engaged, the actress' rep told People.

"I can confirm she is engaged," Stephen Huvane said.

Swiss multimillionaire Busson reportedly gave Thurman a ring with an 8-plus carat center stone surrounded by 20 smaller stones.

Although Thurman lives in New York and Busson lives in London, the two have been dating for about a year.

It will be third marriage for Thurman, whose ex-husbands are Ethan Hawke and Gary Oldman. She has two children from her relationship with Hawke. Busson also has two kids from his prior marriage to supermodel Elle Macpherson.

The couple has not yet set a date for their wedding.
