Here's a look inside the secret Facebook app that only famous people can use

There's a little-known app released by Facebook that, until recently, could only be used by famous people verified by the social network.

It's called Facebook Mentions.

Mentions is a better way for influential people to "keep in touch with their fans," according to the company. It's only accessible to verified Facebook users, a privilege that was previously reserved for celebrities, sports stars, and musicians. You can tell someone is verified because they have a blue tick next to their name.

Since journalists can now be verified too, we downloaded the app to see what it does and how it differs from regular Facebook.
