Prinsloo hid her baby bump in a black maxi dress and floor-length jacket. She also traded her runway heels for black tennis shoes, and topped off the look with several necklaces and a pair of red sunglasses.
Levine also stepped out in a style all his own. The 37-year-old Maroon 5 rocker sported a "Highway to Hell" T-shirt, along with loose-fitted jeans and white and red Nike sneakers. The couple happily held hands as they shopped.
Prinsloo and Levine might be making a big purchase before the baby arrives. ET revealed earlier this week that the two were house hunting, and spent three hours looking for a new home in Pacific Palisades, California, on Saturday. The couple showed up to a prospective property together in their pewter Porsche, and toured various properties with their realtor.
An eyewitness told ET that Levine and Prinsloo "were very helpful and joyful as they left the house," which they described as "very beautiful."
