If it scores 350k+ in the US, it has the WW chart on lock down too.
EDIT: NVM. Katy Perry is doing 500k worldwide. Britney could snatch it if HIAM scores 400k+, the pop bars of the all the countries are MASSIVE, it could probably add a 100-150k to the numbers and have Britney top Katy. I'm not sure. We'll see.
Cant wait to see its performance in charts, and hope it stays more than one week at #1
