This would be such a waste of time AND money. S&M has run it's course and it's time for Rihanna to focus on CKB. Nobody wants to hear Britney's nasally, computerized vocals and watching her dance stiff as a rock attempting to be sexy while shaking those bottle blonde extensions.
Why is Rihanna trying to act like she actually wants a video and this wasn't a desperate a copy and paste job to use Britney's legendary star power to get to #1?
