Aw!

Zayn Malik has tweeted fans thanking them for their birthday messages / PAAll this birthday talk has made us think of the reasons we love Zayn...

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.
