People are CRAAAAAZY.

Rihanna may have been snuggling up to beau Chris Brown at the Grammys earlier this month and ignoring him just a few days later, but one thing's for certain: the "Stay" singer's fans aren't too happy about their hot-and-cold relationship.

On Saturday, Feb. 16, the Barbados songstress was enjoying a night out on the town in London with some pals at hotspot The Box when someone reportedly threw a bottle of Lucozade -- a British energy drink -- in her general direction.

According to reports, the culprit also screamed at the singer about her relationship with Brown, 23.

Rihanna was left with a bloodied right knee that photographers caught just as she left the club at the end of the night. - USMagazine
