Why did Rihanna fall off so badly?

She use to be the #1 RB superstar when she was dating Chris Brown and
shortly after they broke up, but now the only place you ever hear
about her is MTO and other sites thirsty for a story.

Chris Brown was always more talented than her, which is why he got
right back on top of the RB game after he went through a bad stretch.

Beyonce is falling off too.. BET needs to get out of her panties
though! Her songs are wack nowadays!
