Katy Perry just made music history with her iconic old song--Firework, almost exactly 10 years after the song was released! The currently-pregnant star’s Firework is now “the highest certified track by a lead female artist in RIAA history,” according to the Chart Data page on Twitter. The song was released on August 24, 2010, as part of Katy‘s album Teenage Dream and it just received the 12x Platinum certification.
