Katy Perry's Firework has reportedly sold over three million copies in paid downloads, making her the first artist to ever have FIVE songs hit that mark!
Her previous tracks to do so were Hot N Cold, with 4,724,000; California Gurls with 4,560,000; I Kissed A Girl with 3,956,000; and Teenage Dream with 3,255,000!
A HUGE accomplishment! Amazing!
Congratulations, bb! We're so proud of you!
