Rihanna, Ariana Grande and Justin Bieber have all lost over over a million Instagram followers each, following the site cleaning up the site from spambots and fake accounts.
Perhaps most embarassing of all Mase, the 90s rapper still best known for guesting on 'Mo Money Mo Problems' lost 1.5 million of his 1.6 million followers. He has now deleted his accccount.
Kim Kardashian is now the most popular celebrity on Instagram with 22.2 million, despite losing 1.3m fake followers herself.
In clarifying why accounts would be deleted, Instragam announced this week: "We're in the process of fixing an issue that incorrectly includes inactive or fake accounts in follower/following lists. We want to maintain the best possible experience on Instagram, so we do our best to remove spam, fake accounts and other people and posts that don't follow our Community Guidelines.
"As we remove these accounts, some people may notice a decrease in their follower/following counts. When we remove accounts from Instagram that don't follow our Community Guidelines, you may see a decrease in your follower count. This shouldn't affect engagement from authentic accounts that like and comment on your posts."
Rihanna is widely rumoured to be releasing a surprise album in the near future, although no further details have been revealed so far.
