Rihanna cut her knee yesterday after she was heckled when leaving London nightclub The Box.
According to TMZ, Rihanna was leaving The Box in the early hours of the morning when a passer-by started shouting insults at the star - about Chris Brown.
The passer-by allegedly then threw a Lucozade bottle at her, but missed. However, in all the commotion, Rihanna cut her knee on a metal grate.
Rihanna's spokesperson hasn't yet commented on the incident.
Rihanna is in London for Fashion Week, as the star debuted her fashion line for River Island over the weekend.
Guests were greeted by hip hop, smoke machines and champagne at the launch of Rihanna for River Island on Saturday night (February 16).
Her distinctive style was clearly at work in the clothes, which featured bra tops, dresses slashed to the thigh and thigh-high boots. Many of the items utilised a simple monochrome look, while others were made from satin, jersey or denim.
The singer also created a few semi-sheer, elegant dresses that were mainly black but also featured floral patterns.
Speaking of UK fashion in a video, Rihanna says: "The British high street has the most fashionable kids and people in the UK. They just have so much fashion."
