According to reports, Rihanna was attacked by a crazed fan outside of The Box nightclub in London early Sunday morning (Feb. 17).

Sources on the scene say an unidentified fan hurled a bottle of Lucozade then yelled insults at her about Chris Brown.

The singer reportedly fell on a shop grate and grazed her knee and could be seen on the scene cleaning up blood.

Undeterred, she headed inside the club anyway. Can't keep a party girl down!
