On January 31, the 27-year-old model stepped out with baby Jack before linking up with husband Justin Bieber. In the rare mother-son paparazzi photos, Hailey matched Jack's black Doona stroller and carseat with an all-black outfit of her own, pairing relaxed trousers with a chic faux fur coat, skinny sunglasses, and simple black boots.

At this point, Hailey Bieber is the unofficial queen of the jacket. While other celebrity style stars tend to shrink away in the colder months, Bieber shines in a never-ending parade of statement outerwear.

Hailey Bieber is the latest celebrity to put forth her take on winter glamour in New York City. Last night, while out with Justin Bieber and their baby Jack, the Rhode beauty founder added edge to winter style.
