Justin Bieber hit a whopping 50 million followers on the social networking site Twitter earlier this month, just after celebrating his 20th birthday.

He then took to Twitter to thank his fans, known as Beliebers, for reaching the milestone.

 

 

But he’s not the first music artist to reach the big 50. Only last month, Katy Perry also reached 50 million of her own, beating Justin by less than a month!

It looks like the race is now on for the next million. Who do you think will win?
