With the unironic success of new songs such as 'What Do You Mean' and 'Love Yourself' in 2015, Justin Bieber has seen his fanbase grow in both size and range. It seems he's got a way to go before all of his fans are out and proud Beliebers though.
According to new research published by Ticketbis, 21% of his fans would not publicly admit to liking him. They've even broken it into regional areas - Southampton is home to the biggest percentage of closet Bieber fans, with 33% not willing to reveal their fandom.
So, although the 18-30 age group is the biggest growing group of Beliebers in the UK, with 10% liking him more than two years ago, he's going to have to work harder to become completely credible in the eyes of certain music purists.

If you are a Justin Bieber fan - secret or otherwise - he's coming to the UK in October, so you can put on dark glasses and go and see him live. See Justin Bieber's UK tour dates below. For tickets and more information, visit here.
