Katy Perry's Roar On Track To Become Her Biggest Digital Single EVER! Get The Glorious Deets HERE!

Holy guacamole!!!

Roar isn’t just on pace to become the biggest single of 2013, it could very well be the biggest single of Katy Perry‘s CAREER!

In a little over a week, the perfectly poppy Prism track sold over 544,000 digital copies!!! That’s AH-Mazing!

And it’s the best iTunes showing of KP’s career!!!

We knew the song was special when we first laid ears on it, but this is insane!!!

This is the girl behind Teenage Dream, Firework, Wide Awake, and I Kissed A Girl… and this will be her best-selling digital single ever!!?!

Absolutely incredible!!!

Way to go, Katycats — you’ve done your gal proud!!

As a well-deserved reward, we all get to watch Katy slay it this Sunday from the VMA stage, LOLz!!

We can’t friggin’ wait!
