Hailey Bieber cut an athletic figure Friday, when she was spotted in West Hollywood making her way from the gym to lunch with best friend Justine Skye

The model, 23, wore a high-necked cropped grey sweatshirt with a zip turtleneck collar, allowing her bare toned midriff to breathe.

Justine's braids were fastened back in a low ponytail, and she covered up with sunglasses and a black face mask similar to Hailey's.
