Rihanna was attacked last night in London, MediaTakeOut reports, when a "fan" threw a bottle at her while yelling something about Chris Brown.

The bottle reportedly led Rihanna to stumble and cut open her leg. Her bodyguard is said to have gone after the fan and hurt his own leg in the process, leading him to the hospital for treatment. The guy who threw the bottle just went wherever he went. (Some bodyguard — he's the one who goes to the hospital, and lets the guy get away?)

This is probably much ado about nothing, but you can see photos on MTO's site. If that's really the cut on her knee, it's a pretty small one, but it does show blood.
