Dwayne 'The Rock' Johnson, take a bow. The wrestler-turned-actor's insta game is so strong, he's increased his following by 83% this year alone. He now has an admirable 34.3m followers...One for each of the muscles in his right arm.

Taylor Swift has won in the Instagram popularity stakes (as well as all the others). Her army of followers is now 56.9m strong, increasing by 73% in 2015.

Although Nicki Minaj doesn't have the most followers on this list, she's ranked third in terms of increasing her numbers. A 72% increase in 2015 leaves her a cool 39.8m.

She may not have the most popular Instagram pic of 2015 like her sister Kendall, or as many followers and Kim, but in light of a 69% increase in her popularity, Kylie Jenner is certainly catching up. She now has 44.6m followers.

Tay's best mate Selena is right behind her, with 53.2m followers, marking a 67% increase in 2015.

Ariana Grande exploded this year, as did her social media following. A 65% rise in Instagram followers brings her up to 50.2m and counting.

The list wouldn't be complete without Kendall Jenner - who we dubbed the overall winner of Instagram 2015 after she got the most likes on any single instagram picture ever. She now has 42.5m follwers thanks to a 64% increase in her instafame.

Kim Kardashian, selfie queen, had a 61% rise in followers. She now has 53.1m people who hang on her every post - including us.

Now with 52.3m followers, Queen Bey's following has grown by 61%. We think the adorable shots of her beautiful daughter, Blue Ivy might have helped.

The smallest increase on this list - of 59% we might add - goes a long way. Justin Bieber spent 2015 reinventing himself on social media and it paid off. He now has 45.7m adoring followers of his Instagram feed.
