Sienna Miller has moved on from her fling with Brothers & Sisters star Balthazar Getty.

According to reports, the promiscuous actress has wasted little time in conquering her latest hook-up: mediocre actor Josh Hartnett.

Earlier this week, the duo was spotted at London's Shoreditch House.

“They definitely looked like a couple — and a good looking one at that," said a source. "At one point, they were holding hands across the table, but they quickly hid them underneath. They looked really cozy 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."
