Rihanna leaves The Box nightclub in London's Soho at around 3:30AM with model friends Cara Delevingne and Jourdan Dunn

Rihanna, 24, was attacked outside of the Box nightclub in London Monday morning, when a heckler threw an energy drink bottle at the star.

The Daily Mail reports that the assailant was a “crazed fan” who “screamed at [Rihanna] about Chris Brown” before hurling a bottle of Lucozade, a type of energy and sports drink, at the singer. Apparently, the crazed fan was upset with Ri Ri for getting back with Chris. This comes just one week after the Ri Ri appeared at the Grammys with on and off-again boyfriend Chris Brown.

Rihanna was left with a few scratches after a scuffle in London. The singer’s bodyguard also suffered a leg injury in the fight.
