Justin, 28, sported casual style as he looked comfortable in a white sweater. He added white pants with twisted symbols running up and down the stylish trousers.

The Yummy singer accessorized his look with glasses and a backwards blue cap as he was clicked by paps.

Hailey, on the other hand, sported a black sweater, blue jeans and thin black sunglasses protecting his eyes which went perfect for the daytime outing.

The super model walked in black and white sneakers, and styled her brown hair in a pulled-back tight bun.
