1. Those gorgeous eyelashes. Nuff said.
2. That cute quiff he's got going on at the moment.
3. His fashion sense - Zayn always looks super-stylish. We love him rocking the cool chinos and Letterman jacket look.
4. The fact he's sensitive - after he split from Rebecca Ferguson Zayn admitted he was heartbroken. We like it when a guy can get emosh.
Now, seeing as it's Zayn-day, let's spend a few hours drooling over pictures of his fit face.
