Taking advantage of a break from work duties before officially kicking off her Broadway gig, Sienna Miller was spotted making her way around New York City on Wednesday afternoon (October 21).
The "Layer Cake" cutie looked to be in a cheerful mood, chatting on her cell phone as she got a little fresh air while accompanied by her pooch pal Bess.
Meanwhile, the British beauty's Broadway debut in a play called "After Miss Julie" marks its opening night tomorrow (October 22) at American Airlines Theatre, running through December 6th, 2009.
"After Miss Julie" is based off of August Strindberg's 1888 play about "sex and class to an English country house on the eve of Labour's historic landslide in 1945."
