This is borderline offensive (but of course it won't be warned but me calling joan rivers the r word would even though the latter wished death on an entire country)
Rihanna's videography kinda sucks though, let's face it. Russian Roulette is her best and it's not even that great. And she has really bad ones like Te Amo. Her videos never improve the songs at all. She is the world's biggest pop star only because of her discography.
