Not everyone is happy that Rihanna and Chris Brown are back together. The R&B singer was allegedly attacked Saturday night in London by an irate man over her relationship.

According to New York Daily News, RiRi was confronted by an unidentified man outside of The Box nightclub who was upset that she is now back with Breezy. The 'We Found Love' artist was pictured wiping blood with a tissue below her right knee after the incident.

According to an eyewitness, the men yelled at her regarding Rihanna's relationship with Brown and then threw a soft drink at her. During the scuffle, the Bajan beauty fell against a metal object where she cut her knee.

Rihanna's bodyguard did chase after the man but he injured himself as well and had to seek medical attention. Amazingly, the assailant got away with his dastardly deed.

Reps for Rihanna had no comment on the singer's harrowing incident. RiRi was in town to premiere her new fashion line, River Island, during London Fashion Week. It's safe to say that RiRi will beef up her security detail during her travels in London this week.
