Sienna Miller's Sweltering Stroll in NYC

Sienna Miller's Sweltering Stroll in NYC

Heading out for a hot day in the Big Apple, Sienna Miller strolled through the Flatiron neighborhood on Thursday (May 30).

The “Factory Girl” star dressed appropriately in a sleeveless long gray cotton dress and sandals with her hair pulled up off her face.

Currently in post-production, fans can soon see the 31-year-old actress in the upcoming film, “Foxcatcher.”

Costarring Channing Tatum, Steve Carell, and Mark Ruffalo, the drama tells the story of Olympic Wrestling Champion Mark Schultz and how paranoid schizophrenic John du Pont killed his brother, Dave Schultz.
