What do all of these celebs have in common?
Justin Bieber, Nicki Minaj, Angelina Jolie, Diddy, Chris Brown, Rihanna and lots more have all tweeted in support to pledge to stop Ugandan guerilla leader Joseph Kony's enslavement of children.
The campaign revolves around a 30-minute viral video exposing Kony's enslavement and abuse of 30,000 children in Uganda.
The Kony 2012 film has urged internet users to bombard these celebs with tweets to get them to mention Kony - and since Monday the video has already clocked up over 10 million views.
Its objective is to make Kony famous,
"not to celebrate him, but to raise support for his arrest and set a precedent for international justice".
