The fresh-faced star kept things cute and comfortable in baby bump-hugging gray separates while running errands in New York City, and the glowing mom-to-be looked like her second child was definitely on her mind as she rested a hand protectively on her belly. The 32-year-old opted to wear a form-fitting gray tank top with cutouts in the back for her outing, which she paired with a pair of baggy gray capris with rolled hems and black Vans Old Skool sneakers ($65; zappos.com), which are currently enjoying a moment among New York's fashionable street style set.

Layered chain necklaces and bracelets, and a trendy red-and-white checkered choker finished off the House star's errands look. Wilde first announced she and fiancé Jason Sudeikis were expecting a second child last April. VIDEO: Olvia Wilde & Jason Sudeikis' Best Instagram Moments We can't wait to meet baby number 2!
