Rihanna scraped her knee dodging an energy drink bottle hurled at her by a fan. The unidentified man was apparently angry at her for getting back together with Chris Brown, according to tabloid reports. She was leaving London’s Box nightclub after celebrating the launch of her River Island line with Cara Delevingne. Little did the psycho fan know, Rihanna and Brown are supposedly “off” at the moment, having ignored each other at a Los Angeles club last week. But with fans like these, who needs abusive boyfriends?
