The secret Instagram inbox you had no idea existed.

Instagram has a secret inbox and all your dreams of a celebrity secretly contacting you may come true.

After news of the secret Facebook inbox broke and we all got our wallets back, there was a rush to see what other features these social media juggernauts were hiding.

As it turns out, there were a few. Facebook had a secret gaming function and a way to read your messages without sending ‘read receipts’.

This latest exposé follows a similar recipe but differs with how messages are concealed by a ‘blue line’ rather than a whole other inbox.

This is how you access it:

The inbox is not-so-secretly located in the actual inbox feature of the application.

Users can access their messages by clicking their direct message icon - the top right icon that looks like a paper tray.

This will take them to the direct message archive.

The secret inbox will only appear if there is a light blue line above all your other messages.

If there is a light blue line, tap it and you will be taken to a new page titled: Message Requests.

If there is no light blue line, it means there are no unknown users who have tried to contact you.

Messages are stored in this hidden inbox when a user who you don't follow tries to contact you.

When a user you follow sends a direct message, you are notified with a little red number over your inbox tray.

Users on Twitter and other social media sites have discovered the often hilarious benefits of their hidden inbox.

The team at Mamamia have collated some of their favourite responses in the video at the top of the page.
