The singer shot a video for her new single "We Found Love" and broke the rules by going topless. Graham told her to cover up because it was "inappropriate." He then kicked her off the field.
I'm sure Rihanna's decision to go topless was based on how completely relevant it is to the lyrics of the song. Maybe it was during the part where she sings "We found love in a hopeless place"? Hmm... no. Maybe "Yellow diamonds in the light"? No... still wouldn't quite fit. Oh well.
Graham admitted he had "never heard of Rihanna" before that day. Let's face it--He's not missing much.
