Catching up on her correspondence, Sienna Miller was spotted chatting on her mobile phone in New York City earlier today (March 11).

The “Factory Girl” actress looked preoccupied as she paced around outside her boyfriend Jude Law’s hotel building, sporting a blue button-up layered over a grey shirt with black trousers.

Sienna is in the Big Apple to spend time with her main squeeze as he prepares for his gig with “Saturday Night Live” this weekend.

Yesterday, Sienna and Jude were spotted out to breakfast at Café Gitane restaurant, though they took measures to make sure they weren’t photographed together.
