The gurl is unstoppable!

We have to admit we're not surprised to hear Katy Perry's new album,Prism, is about to snag the #1 spot on the Billboard 200 chart because…well…have you heard her album?!

From Roar to By The Grace of God to Unconditionally, she hit this one out of the ballpark!

It's expected that she'll sell 290,000 albums with the possibility of hitting the big 300,000 mark. By reaching the #1 spot, this will be Katy's second #1 album as 2010's Teenage Dream held that spot before.

But that's not the only title the pop princess will score because if she reaches these numbers then she'll be the woman with the largest sales week of this year. This will also be her best ever sales week.

So you know what that means….

…our fave birthday girl is having the BEST WEEK EVER!!!
