Today, Katy Perry has made history!
The singer has become the very first person to reach 100 million followers on Twitter!
Most celebrities have a higher amount of followers on Instagram, but this is the first time that someone has hit the 100 million mark on Twitter.
The site celebrated the occasion by pulling a Facebook and creating a video abut some of Katy's best tweets.
Katy thanked Twitter for "always giving me the opportunity to have a voice" in her own celebratory tweet and is probably pretty chuffed about the whole thing.
She originally joined Twitter in February 2009 and reached 50 million followers by mid-2012.
