Natalie PortmanNatalie Portman is rumoured to be dating British banking heir Nat Rothschild.

The two were spotted dining together at Wilton’s restaurant in London earlier this week but arrived at the restaurant separatedly to avoid being photographed together.

An onlooker told the Daily Mail: “A casually dressed Natalie and a female friend pulled up in a chauffeured car at about 9pm and went into the restaurant. Nat arrived on foot five minutes later.”

“After three hours, Natalie came out with her pal, who was holding hands with Nat’s friend. Then Nat ran down the street, jumped in next to Natalie and they drove off.”

Natalie is currently in the city filming The Other Boleyn Girl.
