Sienna Miller and Josh Hartnett an item?

Our national homewrecker Sienna Miller has found another man to put her claws in.  Only this time he’s not married; I guess the Balthazar Getty publicity made her consider this important detail when looking for a new man.  Actor Josh Hartnett (30) is the lucky one.

The two were spotted together at the Shoreditch House in London.  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.”

Hmm. It almost sounds serious.  I hope Slevin knows what he’s getting into.  Won’t be long before she moves on to the next taken man.
