Rihanna was nothing more than another mere pop star who shook what her mamma gave her in pop vids, until she collaborated with Jay-Z on catchy Umbrella ella ella ey ey, and then everyone wanted a piece of this good girl gone bad. Releasing a few more tunes, Rihanna's life was becoming somewhat enviable until she met her ex boyfriend Chris Brown who beat the shit out of her. She has recovered from the whole thing well with a few more high charting singles and albums. Her hair is currently bright red, not a good look.
