New man for Sienna Miller?

IT doesn’t seem to have taken Sienna Miller long to get over her break-up from Balthazar Getty…

The newly single actress looked like she was moving in on a new Hollywood heartthrob as she shared an intimate evening with Josh Hartnett.

The Rain Man star snuck out for a sneaky date with Sienna, 26, at the exclusive Shoreditch House members’ bar after spending his evening at a nearby charity event.

Our spy said: "They definitely looked like a couple - and a good looking one at that! At one point, they were holding hands across the table, but they quickly hid them underneath.

“They looked really cosy as they dined, gazing into each other's eyes, smiling and laughing. They continued talking and drinking until very late into the evening - there was definitely a buzz in the air.”

The secret date last week came just days after the pair reportedly exchanged phone numbers, and it seems like the couple are already more than at ease with one another.

“Josh was quite dressed down with a beanie hat pulled down over his ears and Sienna was hardly wearing any make-up,” said our Shoreditch spy.

The pair were last seen out a fortnight ago at Jalouse in Kensington shortly after Sienna confirmed her single status after splitting from married Balthazar, who she began dating back in June this year.

Onlookers said she swapped numbers with Josh, 30, after flirting with him during the evening, seeming keen to hook up with the actor again.

Though we're sure Sienna will never be short of offers, we’re just relieved that the new man in her life is single…
