Hailey, 22, is always one to support her man's projects.
The blonde looked great in an oversized, blue, green and yellow stripped shirt that had a cartoon-like bear with Drew's logo on it. She also held her phone which was protected with a Drew phone case.
She accessorized with a pair of black sneakers, a matching cross body bag, sunglasses and her signature gold hoop earrings.
Justin, 25, who secretly married the model in September 2018, also joined his wife on her outing.
The singer wore a pink floral shirt with slouchy beige pants and white sneakers.
The couple, who recently got back from their trip to Japan, held hands as they got out of their car. Justin kept his navy blue and red baseball hat low on his face.
