This is how it's done people: In March, Justin Bieber had 18 million followers on Twitter. Four months and a bestselling album later, that number has climbed to 24.3 million.
Only one other person has broken the 24 million barrier on the social media site: Lady Gaga, who currently has 26.5 million followers.
Most of the top 10 most followed people on Twitter are music stars. They include Katy Perry, Rihanna, Shakira and Britney Spears. Barack Obama is the only other male on the list. He has 17 million followers.
Bieber hit the 24 million milestone last week and celebrated the moment with a tweet: "from a town of 30,000 - on my 18th bday we hit 18 MILLION...and now 4 months later we are at 24 MILLION BELIEBERS!!! #TEAMBIEBER GOES HARD!"
