Sixteen social media stars - also known as influencers - have now agreed to change how they post online.

They are highly prized by businesses for the huge commercial boost they can give to products by endorsing them on sites like Instagram and YouTube.

The UK Competition and Markets Authority wants to regulate how they earn money. Social media influencers must now clearly state if they've been paid or received any gifts or loans in return for their endorsements.

Em Sheldon is a British Instagrammer. She gave some examples of the commercial deals she's done.
