Mmmmm no , those are inflated sales and you know it Katy Cats........

One of the boys passed the 3 millions just one year ago and TD didnt even pass the 6 millions
According to Mediatraffic it's at 5.8 millions....
i think she's a bad album seller , especially TD who had 6 HUGE singles and a re-release

Lol, no it's not, it's been a while since it's at 3M, stop saying garbage.

And TD is at 6M, since Mediatraffic don't count all the countries, let's not act like 5,8M was the exact number.

And stfu with the bad album seller thing, she sells BOTH singles and albums.

Flo Rida & Pitbull are bad albums sellers, Katy is not.

!!!!

Leading pop girl of our generation, only followed by Rihanna

Death at the stupid haters ONLY focusing on the album/single ratio because that's the ONLY thing that they can target. Reach some more haters, I think it's funny.

Why?? Gaga's stans always say that BTW album sold more than 7 m, and BTW single sold over 9.5. Number tell the true, the same according to Mediatrafffic..

A mess, TD already sold more than 300K in US in 2013 .
