Do you know Harry Styles‘ nose from Ariana Grande‘s left eye and Calum Hood‘s ankle? Give this quiz a try and you’ll find out. Some of it is quite difficult, so if you manage to get full points make sure to let us know @maximumpop on Twitter. We’ll be seriously impressed!
If you’ve got them on Snapchat it’ll be much easier, you’ll know their bod like the back of your hand. Quickly, go find them on our Snapchat directory and add them. You can thank us later.
