Either way, they just need to let it do what it's doing now. Release the video the week before, during, or after the BBMAs (which they should perform this at). That's all it needs.

additionally, Bebe sounds good on the chorus... but why didn't Nicki sing it? she would've killed it. I dunno, it just seems like a missed opportunity.
