Sienna Miller: New Mystery Male!

Sienna Miller and a new male friend hang out in the SoHo neighborhood of New York City on Wednesday. The twosome shopped at Face Stockholm, American Apparel and Barney’s Co-op. They were also spotted by the restaurant Balthazar, appropriately enough. (Sienna was also seen smoking a cancer stick.)

Earlier this week, one of her fansites threatened to shut down, saying:

“We do not know the whole story behind this affair, and some may argue it is not our place to judge BUT when Sienna can cavort so publicly and so shamelessly with this man who IS married and does have 4 children (including a baby only a few months old) with his wife, my respect for her goes out of the window.

“One minute she says she wants to be taken seriously as an actress and she’s sick of all the false stories about her in the press … and the next she’s topless on a beach with a married man’s hands all over her – come on Sienna, you know the paparazzi are going to be around. If she was serious about being taken seriously she would, well, not display herself so publicly like this. “
