The First Photos From The Celebrities Who Joined Instagram In 2015

It's been quite a year for new joiners...

As hard as it is to believe, not every single celebrity in the world is on Instagram. And 2015 was the year that everyone from Adele to David Beckham decided to join in the Insta-fun, by creating their own accounts and uploading their very first photos to the social media giant.

We also saw from Caitlyn Jenner and Zayn Malik, who kicked off their Insta-careers with shots of themselves covering magazines, while brothers Liam and Chris Hemsworth opted for more tongue-in-cheek starting photos.

Game Of Thrones actress Emilia Clarke also joined, as well as one unexpected entity - the Royal Family.

Scroll down to see which photos 2015's biggest additions chose to make their entrance...
