Sienna Miller is dating actor Josh Hartnett. Hartnett is currently living in London, while performing in a West End Production of “Rain Man.”

Hartnett and Miller were spotted cozying up at Shoreditch House, an exclusive East London bar. According to the “Daily Dish”, a source revealed, “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 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."
