A year ago Snapchat was the kind of thing you heard about from the younger gen and suddenly it’s got over 200 million users and celebs are ALL over it. Especially Cheryl, who's taken to sharing Snapchats from her Instagram but not sharing her username with anyone... #Savage.

It's no wonder everyone's got on board — it is excellent fun. Not just, as widely thought, for sending naked pics, it’s also entertaining to see what you’d look like as a cat or a dog or a Viking, and to see what Justin Bieber is doing at any hour of the day.

So, first thing’s first — how to use Snapchat?

This bit is pretty simple. Just download the app (which you can search in the App Store), create a log in and go! Just click the camera icon and touch (or hold down for a video) the main circular button, then choose someone from the ‘Your Friends’ section and go. Caption optional.

How to follow celebrities on Snapchat?

It's the same as following other users. All you have to do is tap the ghost icon (that yellow and white thing) which will take you to the main screen and from here click 'Add Friends'. Type in their Username (which are often in their Instagram or Twitter profiles. They’re often just their name so guess if you’re really desperate). When it appears underneath, tap the plus icon next to the name… And you're done — you can see their stories!

And now the important things — celebrity snapchat names. Here’s which celebs to follow and why…
