Uma Thurman was all over her boyfriend Arpad Busson "like a rash" during a recent dinner date.

The 'Kill Bill' actress couldn't keep her hands off her multi-millionaire financier lover - who she has been dating since last July - when they enjoyed an intimate meal at New York's Lever House restaurant last Thursday.

An onlooker said: "She was all over him like a rash. Lots of kissing, touching and groping hands under the table. It was almost as if they were putting on a show for everyone."

Uma - who has two children, Maya, nine, and Levon, six, with ex-husband Ethan Hawke - recently revealed she has no plans to leave New York and live with Arpad in London because she doesn't want to uproot her children.

She said: "Before I had kids, I would constantly move. I've made huge strides for the sake of my dear children so they're not subject to adolescent homelessness from me."

Last year, it was reported Arpad and Uma had got engaged. However, the pair is yet to confirm the news. Uma, 37, has been married twice before, to actor Gary Oldman from 1990 to 1992, and to Ethan, who she filed for divorce from in 2004.

Arpad, 44, dated supermodel Elle Macpherson for 10 years before they split in 2005. The pair has two sons, Arpad Flynn and Aurelius Cy.
