Hartnett, Miller share 'intimate evening'

Josh Hartnett and Sienna Miller have fuelled speculation that they may be an item after sharing an intimate evening together.

Hartnett is currently living in London as he appears in a West End production of Rain Man.

The couple spent an evening together at the exclusive Shoreditch House members bar in London, according to The London Paper.

"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 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."

Miller was first spotted with Harnett at an event in West London shortly after she split from married actor Balthazar Getty.
