Uma Thurman is reportedly romancing Elle Macpherson's ex-boyfriend.

The 'Kill Bill' star, who split from hotelier Andre Balazs in March, was seen canoodling with Swiss banker Arky Busson during a romantic night out.

A source told the New York Post newspaper: "They had their arms wrapped around each other and seemed oblivious to everyone around them."

Uma and Arky - who has two sons with model Elle - first met last month at designer Valentino's 45th anniversary party in Rome.

Uma - who was recently linked to actor-director David White - has two children, eight-year-old Maya and five-year-old Levon, from her five-year marriage to actor Ethan Hawke.

The actress' marriage to Hawke ended in 2004 amid reports he cheated on her with a Canadian model. Uma, 37, then embarked on a three-year on/off relationship with Balazs.

Last year, the actress admitted she was trying to perfect the art of making a relationship work.

She said: "You need to want to be forgiving. The problem is that, if you want to, you'll forgive the unforgivable. I am very perceptive about people, but then if I'm attracted to them, I'm not always looking clearly."

"I'm working on a decoding system - especially for men."
