Here are the 15 people who get the most likes on Instagram

Athletes, musicians, and reality TV stars have the highest number of likes on Instagram.

That's according to a study conducted by Project Know, an online platform for substance abuse education. The study aimed to find out how celebrity Instagram posts affect teens, and how often drugs and alcohol crop up in those posts.

But the research showed that the most-followed users aren't always the one getting the most engagement on their posts. For example, while Selena Gomez is the most-followed person on Instagram with a whopping 115 million followers, her posts don't rack up the most likes - that honor goes to one of the world's most famous soccer players.

Here are the 15 artists, entertainers, and athletes with the highest number of likes on average.
