We'd have to scroll through people's 'Following' section or download a particular app to see if they reciprocated our Insta love.
But with Instagram's latest update, you'll easily be able to know!
Instagram has added a 'follows you' tab that appears on the profiles of people who follow you.
At the moment, the function has only been added to Android phones in certain locations but it's expected that all Instagram users will soon have access to it.
All hail the Instagram gods!
