Kum Kardashian will always be remembered for her sex tape, who wants that kind of fame?
Meanwhile Rihanna is still the fifth best selling female artist of all time.
Remember when Rih would always retweet every dumb chart achievement of hers on Twitter?
Now she keeps delaying her album because she knows she is powerless without radio spamming her. Once so mighty (not really LOL) and now running away scared from Mrs. Puff.
