Sienna Miller & Tom Sturridge's Romantic NYC Retail Romp

They're months away from welcoming their first little one into the world, and Sienna Miller and Tom Sturridge looked happily in love while out in New York City on Tuesday afternoon (March 6).

The "Pirate Radio" actor warmly put his arm around his "Hippie Hippie Shake" gal as the twosome walked from store to store during their Big Apple shopping spree.

The romantic retail romp comes just as Miss Miller's cover issue for British Vogue has been released - in which she speaks about her pregnancy for the very first time.

Of her baby on board, the 30-year-old actress tells, "I'm in my second trimester, so I'm I-can-talk-about-it pregnant, even though I'm under strict instructions not to say anything as it would completely defeat the point of everything I've tried to achieve in the last eight years."

Sienna added that she's doing well and looking forward to the future, as she said, "I'm feeling fine. It's all progressing nicely and it's very exciting. It's nice to start a new decade."
